What this PR does

New clones can wait forever on a golden image whose import keeps failing. CDI v1.66.1 retries ordinary HTTP failures without setting phase Failed.

The guards now also refuse goldens with at least three importer restarts unless they reached Succeeded. kubernetes-nodes and the picker require Running=False; vm-disk refuses during running attempts too. Existing vm-disks and already-cloned pools remain exempt. CDI never lowers the restart count, so a healthy import with three early restarts stays refusable until Succeeded, including while a recreated importer is still starting.

An empty worker-pool StorageClass now resolves to the virtualization default, then the GA Kubernetes default. Beta is a last fallback for the class written explicitly onto a worker disk, not a CDI fallback. The strict same-class policy stays.

This can refuse a previously accepted builtin pool on upgrade. The affected pool has an empty StorageClass at both pool and application level, no cloned disk yet, and a golden on the Kubernetes default while another class is the virtualization default. StorageClass is immutable: point osImage.builtin at a catalog entry on the virtualization default or switch to osImage.factory. Already-cloned pools keep their disk's class.

A VMDisk's own HTTP import, golden-image health checks and imports that hang without restarting remain outside this change.

The Linux unit lane passed on this head.

Release note

fix(vm-disk, kubernetes-nodes)!: refuse new clones of golden images whose import has not succeeded after at least three importer restarts. kubernetes-nodes and the image picker require the importer to be not running; vm-disk refuses during running attempts too. kubernetes-nodes now resolves an empty storageClass to CDI's virtualization default before the Kubernetes default. A builtin pool with an empty class at both pool and application level, no cloned disk yet, and a golden on a different class can now be refused. Point it at a catalog entry on the virtualization default or switch to osImage.factory. Already-cloned pools are unaffected.

Walkthrough

The pull request updates golden-image import handling and StorageClass selection. It adds flux-plunger recovery and shutdown draining, and changes several application charts, CI workflows, and diagnostics tools.

Changes: Golden-image handling

Layer / File(s) Summary
Repeated import failure detection
pkg/registry/core/option/providers.go, packages/apps/vm-disk/templates/dv.yaml, packages/apps/kubernetes-nodes/templates/nodegroup.yaml, internal/controller/workloadmonitor_controller.go
The image provider and disk templates recognize an import that is not succeeded, has at least three restarts, and has a Running=False condition. The workload monitor adds the Running=False condition message to DataVolume status messages.
StorageClass selection and clone checks
packages/apps/kubernetes-nodes/templates/_helpers.tpl, packages/apps/vm-disk/templates/dv.yaml, packages/apps/kubernetes-nodes/tests/*, packages/apps/vm-disk/tests/*
The Kubernetes-nodes chart checks CDI’s virt-class default before Kubernetes and beta defaults. The vm-disk template evaluates CDI clone strategy, StorageProfiles, snapshot classes, and LINSTOR remote-access settings when rendering cross-class clones.

Flux-plunger recovery and shutdown

Layer / File(s) Summary
Recovery and fence lifecycle
internal/controller/fluxplunger/flux_plunger.go, internal/controller/fluxplunger/flux_plunger_test.go, internal/controller/fluxplunger/ssa_ownership_envtest_test.go
Flux-plunger tracks suspension ownership, uses guarded server-side applies and uncached reads, and retains uninstall fences until Helm Controller has handled termination.
Shutdown and uninstall cleanup
internal/controller/fluxplunger/drain.go, cmd/flux-plunger/main.go, packages/system/flux-plunger/templates/*, packages/system/flux-plunger/tests/*
The manager drains fences after shutdown under configured Lease and timeout settings. The deployment enables leader election, and a pre-delete hook attempts to release remaining fences.

Charts and platform behavior

Layer / File(s) Summary
Redis and Kafka configuration
api/apps/v1alpha1/redis/*, packages/apps/redis/*, packages/apps/kafka/templates/*, packages/system/kafka-operator/values.yaml
Redis adds write-replica and acknowledgement-lag settings and uses the same version-mapped image for Sentinels and data pods. Kafka templates derive JVM options from resource limits.
Networking, Multus, and cleanup
packages/core/platform/templates/*, packages/system/multus/*, packages/apps/kubernetes/templates/delete.yaml, packages/extra/etcd/*
The platform guards networking variant changes and passes Multus resource overrides. Multus validates resource values, Kubernetes cleanup removes named resources, and etcd defrag uses the configured quota with compaction disabled.

CI and operations tooling

Layer / File(s) Summary
Retention and workflow checks
.github/workflows/retention.yaml, hack/retention-*, .github/workflows/e2e-proxmox.yaml, hack/proxmox-teardown-contract.bats
Retention resolves packages from the published nightly tree, skips packages linked elsewhere, and records listing or deletion errors. Proxmox workflow staging validates its kubeconfig, and teardown attempts all configured deletes.
Envtest and Chainsaw
Makefile, .github/workflows/pull-requests.yaml, packages/core/testing/images/e2e-sandbox/*
CI runs the flux-plunger envtest target. The sandbox builds patched Chainsaw from source and tests polling through transient API errors.
Diagnostics and other maintenance
hack/cozyreport.sh, packages/apps/kubernetes/images/kubevirt-csi-driver/node.go, packages/system/linstor/images/piraeus-server/patches/*, packages/system/dashboard/images/console/apps/console/src/routes/*
The diagnostics collector adds LINSTOR pool and ZFS dataset evidence. The CSI driver updates NFS publishing behavior, LINSTOR updates snapshot restore state, and Console sidebars include grouped categories except Administration.

Full details: Title check

Explanation

The title names the two main areas changed: vm-disk and kubernetes-nodes guards that refuse golden images whose import keeps failing. The PR adds a signal that treats a DataVolume as failing when it is not Succeeded, has at least three restarts, and has Running=False. The title is specific and matches the main objective (linked issue #4564). It also carries the breaking-change marker, which matches the author's comment that the title is now marked as breaking.

Full details: Linked Issues check

Explanation

[#4564] The guards and image option provider implement the restart-count and Running=False predicate, retain Failed, add focused tests, and preserve the cloned-pool exemption. However, #4564 also requires the decision to cover the same persistent HTTP-import loop for a VMDisk. The PR explicitly leaves that case to the WorkloadMonitor follow-up tracked by #4059. The direct linked issue therefore remains incomplete.

Resolution

Extend the failure detection to VMDisk HTTP imports, or update the directly linked issue requirements before merging. Add automated coverage for that VMDisk case.

Full details: Out of Scope Changes check

Explanation

The PR contains substantial changes unrelated to [#4564]. Examples include Flux plunger shutdown and fence handling, Redis write-safety settings, Kafka JVM sizing, Multus resources, backup-client images, retention workflows, CSI-driver NFS publishing, etcd defragmentation, dashboard categories, and multiple unrelated workflow and documentation changes. These changes do not support the golden-image guard or storage-class objectives.

Resolution

Remove unrelated implementation, test, and documentation changes from this PR, or move them to separate PRs.

Verdict

LGTM

Three golden-image guards get the same new predicate: a DataVolume that is not Succeeded, with restartCount >= 3 and Running=False. It lands in the Go image picker, vm-disk and kubernetes-nodes, and an empty storageClass now resolves to the class CDI actually binds on. I checked the predicate is the same in all three places, verified the CDI behaviour it leans on against the pinned upstream (v1.66.1), mutation-tested the regression tests, and ran the chart's bats siblings against the head merged with current main. Nothing blocks. Three non-blocking notes below.

Findings

  • [MINOR] packages/apps/kubernetes-nodes/templates/nodegroup.yaml:334, empty storageClass now resolves to the virt-default, which can refuse a pool that rendered before this change
  • [MINOR] packages/apps/vm-disk/templates/dv.yaml:38, guard still refuses in the window after a manual importer-pod recreate, and the error text names only back-off
  • [NIT] packages/apps/kubernetes-nodes/templates/_helpers.tpl:421, comment justifying beta-annotation-last describes a path CDI does not take for these DataVolumes

Verification

  • CDI v1.66.1 (kubevirt/containerized-data-importer): status.restartCount is populated from the importer pod, the DataVolumeRunning condition exists, and the classless-claim resolver reads is-default-virt-class then the GA is-default-class (beta never consulted), so the predicate is not inert and the resolver matches CDI. That mechanism is also pinned live by the vminstance chainsaw suite, which gets selected for a vm-disk change.
  • Merged origin/main into the head (clean), then ran the PR-relevant bats on that tree: 34/34 pass, including the directly-edited check-worker-image-catalog-defaults.bats, helm-unit-tests, check-render-matrix, check-values-schema-string-defaults, check-rd-release-prefix.
  • golangci-lint could not run here (binary go1.26 vs repo go1.27.1); go build / go vet / go test ./pkg/registry/core/option/... and the nested api module build are clean.

Recommended follow-ups

  • Nothing required. #4059 (the same hang on a VMDisk's own import) is correctly left open and out of scope.

Findings not anchored to changed lines

These reference code outside this PR's diff (unchanged files, or lines outside a hunk), so GitHub cannot render them inline.

[MINOR] packages/apps/kubernetes-nodes/templates/nodegroup.yaml:334 empty storageClass now resolves to the virt-default, which can refuse a pool that rendered before this change

On an osImage.builtin pool with an empty storageClass and no bound disk yet, the merge base resolved the empty class to the Kubernetes default and wrote that onto the worker disk, so a golden on the Kubernetes-default class produced a working same-class clone. This change resolves the empty class to the class annotated storageclass.kubevirt.io/is-default-virt-class first (_helpers.tpl:431, included here at nodegroup.yaml:334). On a cluster where an admin put is-default-virt-class on a class V that differs from the Kubernetes default K, with the golden on K, the pool now resolves to V, V != K, and the cross-class guard fails the render where it rendered before. Narrow and recoverable, so non-blocking: nothing in-tree sets is-default-virt-class (grep finds only this PR's fixtures) and the stock cozystack default is local, so a stock cluster is unaffected; there is no data loss (a pre-clone pool has no workers), the error is legible, and the new behaviour is arguably correct (CDI would place a classless disk on the virt-default, mismatching the golden). But storageClass is immutable (self == oldSelf), so an affected pool cannot be fixed by edit, only recreated. Worth a release-note line naming this upgrade-time behaviour change for clusters carrying a virt-default annotation; the PR body and release note do not mention it.

[MINOR] guard still refuses in the window after a manual importer-pod recreate, and the error text names only back-off

CDI never lowers status.restartCount (the storage.pod.restarts annotation is written only when the new count is >= the stored one) and sets Running=False for any container state that is not Running, including ContainerCreating and Pending. So after the standard remedy the error text itself points at (fix the source, delete the importer pod to skip the back-off), the fresh importer pod goes Pending then ContainerCreating with restartCount still frozen at >= 3 and Running=False, and the guard keeps refusing the render until that container actually reaches Running; if the node is pulling the importer image or the pod cannot schedule, the refusal persists for that whole window. Non-blocking: the HelmRelease is built with Strategy: RetryOnFailure and an explicit retry interval, so this self-heals as a flap rather than a stuck release, and a genuinely-importing golden (container Running, so Running=True) is never wrongly refused. But the error message (dv.yaml:38, nodegroup.yaml:373, same predicate in providers.go:389-400) attributes the delay solely to the importer back-off, which is not the cause on the manual-recreate path, a word on the new-pod-startup window would make it accurate.

Both error messages now say that a recreated importer pod counts as not running until its container starts, and the chart tests pin that sentence. The image picker in providers.go returns no message, so nothing changes there. The catalog header in kubernetes-worker-image listed only phase Failed as a refusal, it names this case now too.

provisioned years apart carry different ones and Kubernetes still honours both.
The beta predecessor of the Kubernetes annotation is read last, only when no
class carries the current one: CDI does not read it, and a claim CDI leaves
without a class is defaulted by Kubernetes, which honours both.

[NIT] comment justifying beta-annotation-last describes a path CDI does not take for these DataVolumes

The comment reads: "a claim CDI leaves without a class is defaulted by Kubernetes, which honours both." For these DataVolumes CDI does not leave the claim for Kubernetes to default: pvcFromStorage returns ErrStorageClassNotFound and creates no PVC when neither the virt-default nor the GA default is found and spec.storage carries no accessModes, and none of the worker-image / vm-default-images / nodegroup / vm-disk templates set accessModes. So on a beta-only cluster an unnamed golden never gets a PVC and the Kubernetes-side defaulting the comment relies on is never reached. The key ordering itself (beta last) is correct and harmless for the worker disk (the chart writes a resolved class explicitly); only the stated justification is inaccurate, and tests/worker_image_beta_default_class_test.yaml pins it.

Fixed in 64281ba. The comment now says CDI creates no claim in that case, and that the beta annotation matters only because the chart writes the class onto the worker disk. The test header and the commit message carried the same claim and are fixed too.

IvanHunters all three notes are in 64281ba. For the nodegroup.yaml:334 one, the commit and the title are marked breaking now, and the body and release note say which pools it hits and what to do. Only a pool that has not cloned yet is affected, a cloned pool reads its class from its own claim, and a test pins both. The push dropped your approval, could you take another look?

The three golden-image guards (the Go image picker, the vm-disk chart, the kubernetes-nodes chart) get one shared predicate: a DataVolume that is not Succeeded, with status.restartCount >= 3 and the Running condition False. I checked the predicate is the same in all three places, verified the CDI behaviour it leans on against the pinned upstream (v1.66.1), mutation-tested the guard in both the Go suite and the chart tests, and ran the chart's siblings against the head merged with current main. The breaking change is well scoped and documented. Everything below is non-blocking; both prior blockers' actionable halves are resolved.

Findings

  • [MINOR] packages/apps/kubernetes-nodes/templates/_helpers.tpl:477, Empty storageClass now resolves to the virt-default, which can refuse a not-yet-cloned pool that rendered before
  • [MINOR] packages/apps/vm-disk/templates/dv.yaml:38, The restart-count predicate stays armed through an otherwise-healthy long import
  • [NIT] pkg/registry/core/option/providers.go:390, The predicate reads the first Running condition in Go and the last in the charts

Checked and correct

  • CDI v1.66.1 (kubevirt/containerized-data-importer): status.restartCount is populated from the importer pod and never lowered, the Running condition exists, and GetStorageClassByNameWithVirtFallback reads the virt-default annotation first and then the GA default (beta is never read), with the newest creationTimestamp then the name ascending as the tie-break. The predicate and the resolver both match that, and the vminstance chainsaw step pins the two signals on a real unreachable VMDisk. CodeRabbit's tie-break note was correctly withdrawn: lookup returns the classes name-ordered, so strict gt keeps the alphabetically first on a timestamp tie, which is what CDI does.
  • The Go predicate and both chart guards are mutation-tested load-bearing: reverting restarts < 3 reddens the Go test, and widening ge $goldenRestarts 3 reddens the chart tests.
  • The empty-storageClass resolution and the cross-class refusal already exist at the merge base, so they are not introduced here. The only behaviour change for a stock cluster is none: with no virt-default annotation the resolved class is unchanged. Two further edges are CDI-aligned and exotic: a cluster with the GA default on one class and the beta default on a newer different class now resolves to the GA one (CDI ignores beta), and the multi-Running-condition disagreement between the Go and chart predicates is unreachable because CDI keeps one condition per type.
  • No schema, default or enum changed (descriptions only); the RBAC edit is a comment, the existing datavolumes get/watch/list already covers the new status subfields. Shipped defaults keep the pool and its golden on replicated, which check-worker-image-catalog-defaults.bats enforces, so a stock install never meets the cross-class refusal.
  • Merge with current origin/main is clean; go test ./pkg/registry/core/option/..., helm unittest for both charts (66 and 236), and the directly-edited bats pass. Live CI on the head is green, including Unit & controller tests and E2E (in-tree). A local full bats run showed eight unrelated failures that are not about this change: the package-graph and overlay tests pass in isolation (they only broke under contention in the long single-threaded run), and cilium-ipam-migration.bats fails the same way on a clean main checkout in this environment.

[MINOR] Empty storageClass now resolves to the virt-default, which can refuse a not-yet-cloned pool that rendered before

Carried from an earlier round; this is the intended, documented ! change, so a note rather than a request. On a cluster that carries storageclass.kubevirt.io/is-default-virt-class on a class other than the Kubernetes default, with its golden on the Kubernetes default, a not-yet-cloned osImage.builtin pool whose storageClass is empty at both the pool and the application level now resolves to the virt-default and is refused where it rendered before. It is gated to not-yet-cloned pools (a cloned pool reads its class back from its own PVC and keeps rendering), a stock cluster is unaffected because nothing in-tree sets the annotation, and the resolution matches CDI's GetStorageClassByNameWithVirtFallback. One design point for your call: on the builtin path the resolved class is always written explicitly onto the worker disk, so CDI's own fallback never runs for it, and the only consumer of the resolution is the cross-class comparison. Treating an empty pool class as equal to the resolved golden class on the builtin path would render both the case this PR fixes and this one. Non-blocking.

I'm keeping the refusal. Since #4796, vm-disk resolves an empty class the same way and refuses the same cross-class clone. Mapping an empty pool class to the golden's class only in kubernetes-nodes would make the two charts read an empty class differently. It would also put the worker disks on a class nobody picked, while for CDI an empty class means the virtualization default. The affected pool is narrow, and the error and the release note say how to get out of it. If this should change, I'd do it for both charts in one follow-up.

[MINOR] The restart-count predicate stays armed through an otherwise-healthy long import

Carried from an earlier round; the error-text half is now fixed, this is the part that remains. CDI never lowers status.restartCount, so a golden that took three or more importer restarts early in an otherwise-healthy long import stays refusable for the rest of that import: any later moment with the Running condition at False (the importer pod being recreated for a scratch PVC, a node drain, a Pending schedule, an image pull) trips the guard, and in that window a vm-disk create fails to render, the kubernetes-nodes release fails whole for not-yet-cloned pools, and the image drops from the picker. It self-heals as a flap through the HelmRelease retry. The message now names the recreated-pod startup window; worth one more sentence in the known-limits is that a healthy import with three early restarts stays exposed until it reaches Succeeded. Non-blocking.

The known limit in the PR description now says that: a golden with three early restarts stays refusable whenever its importer is not running, until the import reaches Succeeded. I'm not changing the predicate here. The chart keeps no state between renders, so it can't tell a slow healthy import from a stuck one, and a refused render is retried anyway.

[NIT] The predicate reads the first Running condition in Go and the last in the charts

goldenImportFailing returns on the first Running condition it finds, while dv.yaml and nodegroup.yaml iterate and keep the last one. A DataVolume carrying two Running conditions of differing status would make the Go picker and the charts disagree. CDI keeps one condition per type, so this is unreachable in practice; worth aligning only for consistency.

CDI keeps one condition per type, so the Go picker and the charts can't disagree on a real DataVolume. I'm leaving it as is.

Migrate flux-plunger from deprecated APIs.

FieldsV1.Raw, client.Apply, and GetEventRecorderFor are deprecated in the pinned dependencies. The repository does not currently invoke staticcheck, so this is a maintenance refactor rather than a current CI failure.

Disable client-side validation when OpenAPI v3 is unreliable.

When resourceQuotas is configured and an affected cluster fails its OpenAPI v3 check, kubectl can load the OpenAPI v2 document for client-side validation even with --openapi-patch=false. The hook can then exceed the tenant 128Mi default before applying a node pool.

Restore Redis defaults when these values are unset.

The operator applies only the entries present in spec.redis.customConfig with runtime CONFIG SET calls. When a configured value becomes unset, the chart removes that entry but does not send a reset command. Redis can retain the old min-replicas-to-write value and continue rejecting writes. The same transition can retain min-replicas-max-lag instead of restoring 10.

Render 0 and 10 explicitly when the values are unset. Preserve explicit values, including 0.

Set a deadline for the Chainsaw subprocess.

If Chainsaw hangs, CombinedOutput blocks until the Go test timeout. That can delay a failing sandbox build by up to the default 10 minutes. Use exec.CommandContext with a deadline longer than the 10-second assertion timeout. (pkg.go.dev)

Migrate flux-plunger from deprecated APIs.

FieldsV1.Raw, client.Apply, and GetEventRecorderFor are deprecated in the pinned dependencies. The repository does not currently invoke staticcheck, so this is a maintenance refactor rather than a current CI failure.

When migrating to Client.Apply, use []client.ApplyOption, not []client.PatchOption. Preserve the recorder name when calling GetEventRecorder.

Checked on e0dcef7. Nothing blocking from me.

What I verified:

  • CDI v1.66.1: setAnnotationsFromPodWithPrefix (pkg/controller/util.go) only ever raises storage.pod.restarts and sets Running from the container state. getFallbackStorageClass reads the virt default, then the GA default, and never the beta one. The predicate and the resolver match that.
  • The new wait-importer-restarts step ran in this head's E2E and passed in 44s.
  • Locally: go test ./pkg/registry/core/option/... is ok, and helm unittest passes 122/122 for vm-disk and 236/236 for kubernetes-nodes. The branch merges cleanly onto current main.
  • Proxmox: substrate: proxmox pools refuse osImage (nodegroup.yaml:74) and render proxmoxmachinetemplate, so neither the restart guard nor the new default-class resolution reaches them.

One inline note on vm-disk. Two smaller things:

  1. Out of scope here, but relevant to #4059. A source that accepts the TCP connection and then never answers moves neither signal. The GET in createHTTPReader uses a client with no ResponseHeaderTimeout and a context that is only cancelable, and the 10-minute idle pollProgress starts only after createHTTPReader returns. The importer stays Running with zero restarts. A WorkloadMonitor check would need a time component to catch it.
  2. The CodeRabbit summary in the PR body was generated against a stale range after the rebase. It describes Redis replica acks, Multus resources, Console categories, a networking-variant confirmation and HelmRelease uninstall, and none of those is in this diff. Squash commits on main keep the PR body (#4867 has its CodeRabbit block), so that block should go before merge. The "outside diff range" comments in CodeRabbit's last review (flux_plunger.go, migration-hook.yaml) come from the same stale range.

[MINOR] The predicate is false during every importer attempt, and vm-disk checks it only once

CDI sets Running=True whenever the importer container is running (setAnnotationsFromPodWithPrefix), and that includes each retry of a source that is going to fail again. This guard only runs while the disk has neither a DataVolume nor a PVC (line 28). So a VMDisk created during an attempt passes, nothing checks it again, and it waits without a message, as it did before this PR.

How long the window stays open depends on how the source fails:

  • NXDOMAIN, 404 or connection refused: each attempt lasts a few seconds, so the window is negligible. The e2e fixture (vm-disk-e2e.invalid) covers this case.
  • A firewalled mirror that drops SYNs, the usual air-gapped failure: each attempt waits out the 30s dial timeout of http.DefaultTransport. After the third restart the default kubelet back-off is 80s, then 160s, then capped at 300s, so the predicate is false roughly 27%, then 16%, then 9% of the time.

So "any error that makes the importer exit non-zero is caught" holds only while the importer is in back-off. kubernetes-nodes refuses again on its next render until the pool has cloned, and the picker is only advisory, so this mostly matters here. There are two ways to handle it. One is to drop the Running=False term in vm-disk only: a false positive here costs one disk waiting for Succeeded, and the HelmRelease's RetryOnFailure renders it again. The other is to keep the shared predicate and say, in the PR body and in this comment, that a disk created while an attempt is in flight is not caught.

Marian Koreniuk (@themoriarti) I took the first option: vm-disk now refuses a golden that isn't Succeeded after three importer restarts, running or not. In CDI v1.66.1 setAnnotationsFromPodWithPrefix sets Running=True whenever the importer container runs, however that attempt ends, so the DataVolume can't tell a retry that will fail from a healthy run. The cost is a healthy import with three early restarts. A new disk on it is refused until the import succeeds, and RetryOnFailure renders it again. kubernetes-nodes and the picker keep the Running=False term. The error text, tests, e2e comment and PR body are updated, and the body no longer claims the shared predicate catches every failure.

CDI moves an import to Failed only on a fatal error such as a checksum
mismatch. An unreachable URL restarts the importer with back-off while
the DataVolume stays in progress, so the Failed check let such a golden
through and the clone waited forever. Treat an importer that restarted
at least three times as failing too, whether or not it is running now.
CDI reports every importer attempt as running, including one that is
about to fail again, and the chart checks the golden only until the
disk exists, so a disk created during an attempt would otherwise pass
and wait unnoticed. A healthy import with three early restarts is
refused until it succeeds; the release retries the render.

The worker image guard refused only a golden in phase Failed, which CDI
reaches on a fatal error such as a checksum mismatch. An unreachable URL
restarts the importer with back-off while the DataVolume stays in
progress, so a pool pinned to such a golden waited forever for its first
disk. Refuse an importer that restarted at least three times and is not
running, under the same already-cloned exemption as Failed.

CDI moves an import to Failed only on a fatal error such as a checksum

its importer restarts with back-off while the DataVolume stays in
progress. Drop a golden whose importer restarted at least three times
and is not running, the test the kubernetes-nodes chart applies before
cloning.

…n default

CDI binds a kubevirt-content DataVolume that names no class on the
class annotated storageclass.kubevirt.io/is-default-virt-class before it
falls back to the Kubernetes default. The worker image guard resolved an
empty class to the Kubernetes default only, so on a cluster carrying
both it compared the golden against a class the golden was not on and
refused a pool that matched it.

CDI's fallback reads only the GA default annotation, so the beta one no
longer ties with it: a class carrying only the beta annotation is picked
only when no class carries the GA one. CDI then creates no claim at
all for a DataVolume naming neither a class nor access modes, so such a
pool gets that class only because the chart writes it onto the worker
disk.

The resolution also refuses a pool that rendered before: one with an
empty class that has not cloned a disk yet, whose golden is on the
Kubernetes default, on a cluster where another class carries the
virtualization default. Its storageClass is immutable, so it has to
point osImage.builtin at a catalog entry on the virtualization default
or switch to osImage.factory. A pool that already cloned reads its
class back from its own disk's claim and keeps rendering.

The worker image guard, its error message and the storageClass docs
said CDI cannot clone across StorageClasses and always falls back to a
host-assisted copy. CDI falls back only when the two claims have
different CSI drivers or volume modes; with one driver it asks that
driver for a clone into the other class. The guard stays, the reason it
gives is corrected, and the docs name the virtualization default class
an empty storageClass now resolves to.

Signed-off-by: Aleksei Sviridkin <[email protected]>
The kubernetes-nodes guard and the image option list call an import
failing once its importer has restarted three times and is not running,
and the vm-disk guard once it has restarted three times, because CDI
keeps an unreachable URL in progress instead of moving it to Failed.
Assert that CDI reports both on the DataVolume of the unreachable
VMDisk, so a CDI change that stops doing so turns this suite red rather
than leaving the guards blind.

## What this PR does

A VMDisk created from `source.image` with a `storage` smaller than its
golden image never comes up. CDI v1.66.1 checks a clone against its
source in `validateClone`
(`pkg/controller/datavolume/pvc-clone-controller.go`) before it creates
the target claim. When the source PVC is in `Block` mode and requests
more than the DataVolume, CDI records `CloneValidationFailed` ("target
resources requests storage size is smaller than the source"), creates no
claim and leaves the DataVolume `Pending` for good. The webhook admits
such a DataVolume, so nothing fails at install. Raising `storage`
afterwards does not help either, because the chart renders an existing
DataVolume's spec as it is (CDI does not let it change) and the resize
hook only patches a claim that exists.

This is the default path. Every image in `vm-default-images` is 20Gi on
`replicated`, the StorageProfile CDI builds for the LINSTOR driver puts
`Block` first, and the chart defaults `storage` to 5Gi. Seen on a v1.6.4
cluster with CDI v1.66.1. A 10Gi disk from a 20Gi golden image sat
`Pending` with `CloneValidationFailed` while its release kept timing
out, and raising the disk to 25Gi left the DataVolume at 10Gi. The only
way out is to delete the disk and create it again at 20Gi or more.

The chart now refuses such a disk at render time, before any DataVolume
exists, with a message that names both sizes and the minimum to set, for
example `storage 5Gi is smaller than golden image
"vm-default-images-ubuntu" (20Gi), so CDI refuses to clone it and the
disk would stay pending forever. Set storage to 20Gi or more.` It
compares what CDI compares, the golden PVC's request against the disk's
request in bytes, and first raises the disk's request to the target
StorageProfile's `cdi.kubevirt.io/minimumSupportedPvcSize` the way
`GetEffectiveStorageResources` does. For an empty `storageClass` the
target is the class the check from #4796 already resolves, the default
virt class or else the Kubernetes default.

Nothing is compared, and the disk renders as before, when the golden PVC
cannot be read (under `helm template`, or before CDI created it), when
the golden PVC is in `Filesystem` mode, and for any source other than
`image`. For a `Filesystem` source CDI sizes a `Block` target from the
virtual size of the image inside it and otherwise compares requests
inflated by a per-class filesystem overhead, neither of which the chart
reproduces. An existing disk is exempt, as for the other golden checks,
since its DataVolume spec cannot change anyway.

Not covered here. A `source.disk` clone into a smaller disk goes through
the same CDI check and still renders. The chart default of 5Gi stays
below every default image, so a disk created from one at the default
size is now refused with the message above instead of hanging. Whether
the default should follow the images is a separate decision.

A new helm-unittest suite, `tests/dv_golden_size_test.yaml`, has 15
cases. It pins the refusal at the chart default against a 20Gi `Block`
golden with the whole message, the equal and the larger size, the
comparison in bytes (`21G` is refused against `20Gi`, `20480Mi`
renders), a StorageProfile minimum that covers the golden and one that
stays below it, the minimum read from the default class for an empty
`storageClass`, and the cases that render as before, a `Filesystem`
golden, no cluster, a golden PVC that does not exist yet, a disk without
a size, an existing disk, an `http` and an `upload` source. Against the
template on main the 3 refusal cases fail and the other 12 pass. Six
mutations of the new block each turn at least one case red (any volume
mode compared, the minimum dropped, the minimum read from the requested
class only, no check that `storage` is set, an equal size refused, sizes
compared as strings). `helm unittest` passes 129 of 129 for vm-disk,
against 114 on main, with helm-unittest 1.1.2 as CI pins it. Merged with
the current heads of #4802 or #4955, which touch the same template,
vm-disk passes 137 and 131 cases. `helm template` without a cluster
renders an image disk at 5Gi as before. I have not run it on a live
cluster.

The commit does not cherry-pick onto release-1.6 or release-1.7. Neither
carries the check from #4796 it builds on, and release-1.6 has none of
the golden checks, so a backport would be an adapted change.

### Screenshots

Not a UI change.

### Downstream repositories

Template and tests only. No values, schema, README, defaults or
`ApplicationDefinition` change. The golden images guide on the website
already creates its example disk at the image's 20Gi.

### Release note

```release-note
fix(vm-disk): a new disk from a golden image is now refused at render time when its storage is smaller than the image, with a message that names both sizes. Before, CDI refused the clone with CloneValidationFailed, the disk stayed pending forever, and raising its storage afterwards did not help. The default images are 20Gi and the default storage is 5Gi, so a disk from one of them needs storage set to 20Gi or more.
```

## Summary by CodeRabbit

* **Bug Fixes**
* Disk sizes are now checked against the size of Block-mode golden
images when cloning. If the requested size is too small, it is increased
to the target storage profile’s minimum supported size when possible;
otherwise, rendering fails with an error that states the required size.
* Size comparisons account for actual byte capacity, so equivalent size
units are handled correctly. Filesystem-mode sources and other disk
sources are unaffected.
