On the kubevirt substrate resources.cpu is written into domain.cpu.cores as spelled and decoded as YAML, so "010" gives the VM eight cores, while the cluster-autoscaler capacity annotation parsed the same string as decimal ten (capacity.cluster-autoscaler.kubernetes.io/cpu: "9000m" on a node that offers 7000m). This is the inconsistency reported in #4554 and in the comment on #4546.

  • The YAML-decoded value the range check already computes is kept, and on kubevirt the capacity annotation and the reserved-CPU check start from it.
  • The kubelet reservations are not touched. The worker machineconfig (_talosconfigtemplate.tpl) sizes them from the raw string read as a decimal, and the TalosConfigTemplate name is a hash of that config, so reading the decoded value there would roll every leading-zero pool once. Instead the annotation subtracts the reservations the machineconfig really carries from the cores the VM really has: for "010" that is 8000m − 2 × 500m = "7000m", the node's real allocatable, while "8" keeps "7200m" (2 × 400m). Tests pin both sides: the annotation and the bootstrap configRef name in resources_cpu_test.yaml, and systemReserved.cpu / kubeReserved.cpu in the machineconfig in talos_worker_config_test.yaml.
  • No pool rolls. Checked by rendering nodegroup.yaml on main and on this branch for nine spellings ("2", 2, 2.0, "2.0", "+2", "1e1", "010", 999999, 4294967295): the only difference is the capacity annotation of the "010" case, so the KubevirtMachineTemplate name and the TalosConfigTemplate configRef stay as they are. The machineconfig template itself is not changed.
  • Proxmox parses the quantity as decimal for the machine template and for the reservations alike, so it never had the inconsistency and is unchanged (pinned by a test).
  • The resources description says the value is decoded as YAML, what that means for a leading zero, and that the reservations still read it as a decimal. README, schema, the RD and the Go type are regenerated from it.

This closes #4554 without the migration and the render-time refusal it proposes. A refusal at render breaks a stored pool on its next upgrade, a pattern in the OpenAPI schema breaks every update of an existing CR, and a platform-wide migration over every KubernetesNodes and parent nodeGroups entry is a lot of blast radius for a spelling nobody has reported in a live cluster. With this change the autoscaler plans for the node the VM really is. What is left of a leading zero is the octal reading itself and reservations sized from the decimal value, and both are documented. The unquoted zero of the issue is already harmless: it is falsy, counts as unset, and renders the same bytes as an absent field. If a migration is still wanted, please reopen.

Verified with helm unittest . in packages/apps/kubernetes-nodes (38 suites, 233 tests, 12 snapshots; pointing the annotation back at the decimal string turns the "010" case red with 9000m), make generate (no diff), and a trial merge with #4973 (clean, 243 tests green).

Closes #4554

Summary by CodeRabbit

  • Bug Fixes
    • KubeVirt VM sizing and autoscaler capacity now reflect YAML-decoded CPU values. For example, "010" represents eight VM cores, while kubelet reservations interpret it as decimal ten. "8" and "10" yield 7200m and 9000m of autoscaler capacity, respectively. Proxmox continues to interpret "010" as ten cores, yielding 9000m of capacity.
  • Documentation
    • Clarified explicit worker CPU and memory sizing behavior, including how leading-zero CPU values affect VM sizing, reservations, and capacity calculations.

Explanation

The title clearly describes the main KubeVirt change: deriving autoscaler capacity from the VM's actual decoded CPU core count. It does not mention reservation sizing, but it remains specific and directly related to the changeset.

Full details: Out of Scope Changes check

Explanation

The changed template, CPU tests, Talos reservation tests, Proxmox regression test, and regenerated documentation all address the CPU parsing and sizing behavior in [#4554]. The changes have a direct connection to the linked issue. No unrelated product area is shown.

Full details: Docstring Coverage

Explanation

No eligible functions found in the changed files. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 0 functions across 1 files. (7 skipped: 7 unsupported.)

Full details: Linked Issues check

Explanation

Active direct issue [#4554] requires a numbered migration for stored KubernetesNodes and parent nodeGroups values, followed by render-time rejection of leading-zero and unquoted-zero resources.cpu. The diff instead preserves these behaviors. It renders "010" as eight cores and treats unquoted zero as unset. The diff shows no migration or rejection implementation.

Resolution

Implement and test the required numbered migration. Remove unquoted cpu: 0, rewrite leading-zero values to their YAML-decoded decimal value, and log each rewrite. Then reject both forms during rendering.

GitHub cozystack/cozystack issue 4554 leading zero resources.cpu migration PR 4974

💡 Result:

**Issue #4554 is addressed by PR #4974, but not by the migration originally proposed.**

The issue flagged that `resources.cpu: "010"` was interpreted as 8 cores by the KubeVirt VM but as 10 by kubelet reservations and the autoscaler. Its proposed fix was to migrate stored values, then reject leading-zero and unquoted-zero inputs. (GitHub issue 4554 in cozystack/cozystack (link omitted to avoid creating a cross-reference))

PR #4974 instead makes KubeVirt reservations and the autoscaler use the same YAML-decoded CPU value as the VM. Thus `"010"` consistently means 8 cores, without changing the machine template or rolling the pool; it also treats unquoted `0` as unset. The PR says a migration and render-time rejection were avoided to reduce upgrade risk and migration blast radius. (GitHub pull request 4974 in cozystack/cozystack (link omitted to avoid creating a cross-reference))

**Status caveat:** As of October 19, 2026, the PR page shows #4974 as **open**, not merged. (GitHub pull request 4974 in cozystack/cozystack (link omitted to avoid creating a cross-reference))

Use the decoded KubeVirt CPU value in the TalosConfigTemplate.

For a quoted KubeVirt value such as "010", nodegroup.yaml decodes the VM to 8 cores and computes 400m automatic reservations. _talosconfigtemplate.tpl still passes the raw value to kubernetes.cpuToMillicores, which converts it to 10000m and computes 500m reservations. The Talos worker therefore reserves 1000m while the autoscaler annotation advertises capacity using 800m of reservations.

Preserve the raw quantity for Proxmox, but decode it for KubeVirt in this shared Talos configuration path.

Marian Koreniuk (@themoriarti) NOT LGTM. The kubelet reservations the worker actually gets still read "010" as ten cores, and the branch conflicts with main.

Business context: a leading-zero resources.cpu gives the VM one core count and the autoscaler and the kubelet reservations another (#4554).

B1: the reservations in the Talos machineconfig do not change.

The chart computes the reservations twice. The copy in nodegroup.yaml is the one this PR changes, and it feeds the capacity annotation and the reservation checks. The copy in templates/_talosconfigtemplate.tpl:103-125 is untouched, and that is the one that writes systemReserved and kubeReserved into the worker machineconfig. With cpu: "010" on this head the VM gets 8 cores, the machineconfig reserves 500m + 500m (5% of decimal 10), and the annotation says 7200m. Real allocatable is 7000m, so the autoscaler still plans for more than the node has, now by 200m instead of 2000m. With cpu: "8" the machineconfig carries 400m, so "exactly as for the octal spelling" in the new test holds for the annotation only. This is the open CodeRabbit thread on line 762, and no test asserts the machineconfig reservations.

Either fix has a cost the body has to state. If _talosconfigtemplate.tpl reads the decoded value, the TalosConfigTemplate hash changes for leading-zero pools. I tried it: "010" then gets the bootstrap configRef kubernetes-myk8s-md0-5a5adf instead of -c570c9, so those pools roll once and "no pool rolls" stops being true. The option that rolls nothing is to keep the machineconfig as it is and compute the annotation as the decoded cores minus the reservations the machineconfig really carries. I'm fine with either. Whichever you pick, please add an assertion on systemReserved.cpu for "010" and fix the title and body, which today say the reservations follow eight cores.

B2: conflict with main.

The only conflict is the generated one-line openAPISchema in packages/system/kubernetes-nodes-rd/cozyrds/kubernetes-nodes.yaml, which main changed in 941b50c. A rebase plus make generate in the package resolves it.

What I checked on a trial merge with main (the RD conflict left aside, since the chart tests don't read it): helm unittest is green, 38 suites and 231 tests, and reverting the ternary turns the leading-zero test red. On Proxmox the annotation and the machineconfig agree (9000m and 500m for "010"). The annotation change alone does not roll anything.

It merges cleanly with #4973 and #4860, and the three together pass helm unittest (241 tests).

…ctually gets

On the kubevirt substrate resources.cpu is written into domain.cpu.cores
as spelled and decoded as YAML, so "010" gives the VM eight cores, while
the cluster-autoscaler capacity annotation parsed the same string as
decimal ten. The autoscaler then planned 9000m on a node that offers
7000m.

Keep the YAML-decoded value the range check already computes and start
the capacity annotation and the reserved-CPU check from it on kubevirt.
The kubelet reservations stay as they are: the worker machineconfig
sizes them from the decimal string, and the TalosConfigTemplate name is
a hash of that config, so changing them would roll every leading-zero
pool once. The annotation therefore subtracts the reservations the
machineconfig really carries (2 x 500m for "010") from the cores the VM
really has, which is the node's real allocatable. Neither template name
changes for any spelling, so no pool rolls. Proxmox parses the quantity
as decimal on both sides and is unchanged. The field description says
the value is decoded as YAML and that the reservations still read it as
a decimal.

This closes cozystack#4554 without the migration and the render-time refusal it
proposes: a refusal breaks stored pools on their next upgrade, a schema
pattern breaks updates of existing CRs, and a platform-wide migration of
every KubernetesNodes and nodeGroups entry is a lot of blast radius for a
spelling nobody has reported in a live cluster.

Closes cozystack#4554

Aleksei Sviridkin (@lexfrei) thanks. I took the no-roll option for B1 and rebased for B2.

B1: _talosconfigtemplate.tpl is unchanged, so the machineconfig keeps sizing the reservations from the decimal string and no TalosConfigTemplate name moves. In nodegroup.yaml the reservations went back to main's reading, so they match the machineconfig by construction. Only the capacity annotation and the reserved-CPU check start from the decoded cores. "010" now gives 7000m (8000m − 2 × 500m, the real allocatable), and "8" stays at 7200m. New assertions: systemReserved.cpu / kubeReserved.cpu in the machineconfig for "010" (500m) and "8" (400m) in talos_worker_config_test.yaml, and in resources_cpu_test.yaml the "010" bootstrap configRef pinned to kubernetes-myk8s-md0-c570c9 next to the annotation. Pointing the annotation back at the decimal string turns the "010" case red (9000m). The title, body, commit message and field description no longer say the reservations follow eight cores. The description now says they read the value as a decimal.

B2: rebased on main ae9e7c4 and ran make generate. No generator drift.

Checked on f791332: helm unittest is 233/233. I rendered the nine spellings on main and here, and they differ only in the "010" annotation (9000m → 7000m). The trial merge with #4973 (0e77e2b) is clean and passes 243/243.

Marian Koreniuk (@themoriarti) LGTM. The blockers from my last review are fixed.

The capacity annotation now matches what the node really offers. For "010" the VM gets cores: 010 (8), the machineconfig keeps 500m + 500m, and the annotation is 7000m. I rendered twelve spellings on main 5c564f9 and here. The only difference is that annotation for "010" (9000m → 7000m), so no template name moves. Pointing the annotation back at the decimal value, or dropping the default $effectiveCpu fallback, fails a test. This also settles the CodeRabbit thread on the annotation.

The branch merges cleanly with main now, and make generate leaves no drift.

One thing is not blocking. The reserved-CPU check now also starts from the decoded cores, and no test covers that: pointing it back at $effectiveCpu keeps all 233 tests green. It does change behaviour. "010" with systemReservedCpu: "4" and kubeReservedCpu: "4500m" renders on main (annotation 1500m) and fails here with "must be less than effective node CPU (8 cores)". The refusal is right, since 8.5 cores of reservations do not fit on 8, but a test case would pin it.

helm unittest passes on a trial merge with main (38 suites, 233 tests), and with #4973 merged in too (243 tests). The two PRs do not conflict.

…ctually gets (#4974)

On the kubevirt substrate `resources.cpu` is written into
`domain.cpu.cores` as spelled and decoded as YAML, so `"010"` gives the
VM eight cores, while the cluster-autoscaler capacity annotation parsed
the same string as decimal ten
(`capacity.cluster-autoscaler.kubernetes.io/cpu: "9000m"` on a node that
offers 7000m). This is the inconsistency reported in #4554 and in the
comment on #4546.

- The YAML-decoded value the range check already computes is kept, and
on kubevirt the capacity annotation and the reserved-CPU check start
from it.
- The kubelet reservations are not touched. The worker machineconfig
(`_talosconfigtemplate.tpl`) sizes them from the raw string read as a
decimal, and the TalosConfigTemplate name is a hash of that config, so
reading the decoded value there would roll every leading-zero pool once.
Instead the annotation subtracts the reservations the machineconfig
really carries from the cores the VM really has: for `"010"` that is
8000m − 2 × 500m = `"7000m"`, the node's real allocatable, while `"8"`
keeps `"7200m"` (2 × 400m). Tests pin both sides: the annotation and the
bootstrap `configRef` name in `resources_cpu_test.yaml`, and
`systemReserved.cpu` / `kubeReserved.cpu` in the machineconfig in
`talos_worker_config_test.yaml`.
- No pool rolls. Checked by rendering `nodegroup.yaml` on main and on
this branch for nine spellings (`"2"`, `2`, `2.0`, `"2.0"`, `"+2"`,
`"1e1"`, `"010"`, `999999`, `4294967295`): the only difference is the
capacity annotation of the `"010"` case, so the
`KubevirtMachineTemplate` name and the TalosConfigTemplate `configRef`
stay as they are. The machineconfig template itself is not changed.
- Proxmox parses the quantity as decimal for the machine template and
for the reservations alike, so it never had the inconsistency and is
unchanged (pinned by a test).
- The `resources` description says the value is decoded as YAML, what
that means for a leading zero, and that the reservations still read it
as a decimal. README, schema, the RD and the Go type are regenerated
from it.

This closes #4554 without the migration and the render-time refusal it
proposes. A refusal at render breaks a stored pool on its next upgrade,
a pattern in the OpenAPI schema breaks every update of an existing CR,
and a platform-wide migration over every `KubernetesNodes` and parent
`nodeGroups` entry is a lot of blast radius for a spelling nobody has
reported in a live cluster. With this change the autoscaler plans for
the node the VM really is. What is left of a leading zero is the octal
reading itself and reservations sized from the decimal value, and both
are documented. The unquoted zero of the issue is already harmless: it
is falsy, counts as unset, and renders the same bytes as an absent
field. If a migration is still wanted, please reopen.

Verified with `helm unittest .` in `packages/apps/kubernetes-nodes` (38
suites, 233 tests, 12 snapshots; pointing the annotation back at the
decimal string turns the `"010"` case red with `9000m`), `make generate`
(no diff), and a trial merge with #4973 (clean, 243 tests green).

Closes #4554

## Summary by CodeRabbit

* **Bug Fixes**
* KubeVirt VM sizing and autoscaler capacity now reflect YAML-decoded
CPU values. For example, `"010"` represents eight VM cores, while
kubelet reservations interpret it as decimal ten. `"8"` and `"10"` yield
`7200m` and `9000m` of autoscaler capacity, respectively. Proxmox
continues to interpret `"010"` as ten cores, yielding `9000m` of
capacity.
* **Documentation**
* Clarified explicit worker CPU and memory sizing behavior, including
how leading-zero CPU values affect VM sizing, reservations, and capacity
calculations.

### Release note

```release-note
fix(backupstrategy-controller): the ClickHouse (Altinity) and RabbitMQ backup strategy Pods now run a dedicated `backup-http-client` image (alpine + curl + jq + ca-certificates, non-root, ~7 MB) instead of the 349 MB `platform-migrations` image. Air-gapped mirrors need the new `ghcr.io/cozystack/cozystack/backup-http-client` repository.

fix(e2e): a chainsaw assert in the e2e suites keeps polling through a transient API error such as an etcd leader change, instead of failing the suite long before its timeout.

fix(ci): use GITHUB_TOKEN to start the initial packages build when freezing a release line

fix(etcd): the tenant etcd alert etcdHighNumberOfFailedGRPCRequests now counts only the gRPC codes that the etcd mixin and the platform copy of the alert count, so the Canceled watch streams of a Kubernetes API server that stops no longer fire it on every etcd member.

fix(tcp-balancer): HAProxy now takes its fd and thread caps from the replica's memory and CPU limits instead of the node, so a t1.nano balancer is no longer OOMKilled on nodes with many CPUs. maxconn follows the memory limit at about 16 connections per MiB, 2035 on t1.nano, and the pods roll once on upgrade.

fix(kubernetes): the Proxmox cloud-controller-manager now runs v0.16.1, and the Proxmox CCM and CSI driver images are pinned by digest. The v0.15.0 tag referenced before was re-pushed upstream to a build that panics on start, which left every new Proxmox worker with the uninitialized taint.

fix(marketplace): a tapped repository is pinned to a digest instead of following a mutable tag, so moving the tag upstream no longer changes what runs in the cluster; connect accepts oci://...@sha256:... and an optional keyless cosign verify policy (anchored to an exact identity and preserved across re-connects), and with verify flags the CLI verifies the signature and pins the verified digest at tap time.

fix(dashboard): tenant name in the tenant list links to its detail page now (where Delete is), and top level tenants get their Edit button back.

fix(cilium): the IPAM migration hook no longer fails with "Argument list too long" on clusters with more than a few nodes, which blocked the cilium upgrade and every package that depends on networking.

fix(kubernetes): the OIDC bootstrap Job no longer fails to start for a tenant cluster with about 240 or more oidc.users, the bindings now come from a ConfigMap the Job mounts.

fix(clickhouse): a RestoreJob now restores the archive its Backup was taken as, not the newest one. New Backups record the archive name, Backups taken before this release are restored best effort from the newest archive stamped no later than their takenAt, with a warning in the restore pod log. A ClickHouse BackupJob created again under a name whose Backup still exists now fails instead of reporting that Backup as its result.

fix(backups): the backup controller now re-renders the Velero BSL, the default backup strategies and the platform bucket's credentials Secret when their S3 endpoint is stale, so after the platform bucket's BucketAccess is re-granted for a new publishing.host, backups move to the new endpoint without forcing releases by hand.

fix(securitygroups): a SecurityGroup with attachments and no rules no longer leaves an invalid CiliumNetworkPolicy behind; its backing policy is now accepted by Cilium and still allows or denies nothing.

fix(postgres): the init script renders the declared databases in a stable order, so an upgrade that leaves the databases unchanged no longer rewrites the init-script Secret.

fix(mariadb-operator): the MariaDB operator now uses the platform's networking.clusterDomain instead of a hard-coded cozy.local, so replication and User/Database/Grant reconciliation work on clusters with a non-default cluster domain.

fix(redis): an instance with `replicas: 1` now runs one Sentinel instead of three, without a Sentinel PodDisruptionBudget; on upgrade, the PDB the operator created earlier is deleted. Instances with two replicas or more are unchanged.

fix(lineage, kubernetes): the virt-launcher pods of Kubernetes worker nodes are now resolved to their Kubernetes application and marked as managed by Cozystack, so a SecurityGroup attached to a Kubernetes cluster now applies to its worker nodes, not only to its control plane.

fix(api): tenant quota admission now counts the parent pool's usage of extended resources and hugepages, so a child tenant can no longer get a share the parent has already used. After upgrading, updates to existing tenants may be rejected if their quota for these resources exceeds the parent's remaining budget. This includes updates that leave the quota unchanged.

fix(postgres): a Postgres BackupJob now fails as soon as its CloudNativePG Backup fails, with the recorded error, instead of after 30 minutes, and a BackupJob waiting on a CloudNativePG Backup reports a WaitingForCNPGBackup condition with the Backup's phase.

fix(postgres): databases now refuses the PostgreSQL system databases postgres, template0 and template1, and the init job never runs DROP DATABASE on them. A system database a previous version took over is handed back to the superuser on the next upgrade (event trigger removed, ownership and public schema restored, its <db>_admin and <db>_readonly roles dropped). A release that declares one of them must remove the entry before upgrading.

fix(mariadb): a MariaDB BackupJob or RestoreJob whose operator Job failed now ends Failed instead of Succeeded, and a failed backup no longer creates a Ready Backup without an archive. Backups created by failed runs before this fix are not removed; restoring from one can fail or select another dump from the shared prefix.

fix(kubernetes, monitoring): the vmagent of tenant Kubernetes clusters now writes to the tenant's vminsert and labels series with the owning tenant instead of `cozy-monitoring`. Previously no tenant cluster metric reached the tenant's Monitoring.

### Release note

```release-note
fix(seaweedfs): bucket users granted together could get S3 keys that never work (403 InvalidAccessKeyId). COSI driver is bumped to v0.4.0, which writes each grant to per-identity IAM file.
```
Maxim Kitsunoff (kitsunoff) pushed a commit to kitsunoff/cozystack that referenced this pull request Nov 13, 2026
On 1.6, seven of the twelve originals rule 6 holds back build on code
the line never got: cozystack#5071 changes files cozystack#3940 added on main, cozystack#4974
reads a variable only cozystack#4386 defines. Each conflicts on every run, and
nothing tells a maintainer which missing pull request the conflict
comes from, which every human backport so far had to work out by hand.

For each original the policy takes and nothing carries, run now reads
what it builds on from git alone. A modified or deleted file the line
lacks is named by the first-parent commit on main that added it (V1).
A removed or changed line is blamed at M^1, mapped to the first-parent
commit that brought the blamed commit, and kept only while its text,
edges trimmed, is absent from the line's file (V2c), so a hand backport
under another SHA clears it. Generated files and the keys
update-crd.sh writes into an ApplicationDefinition are not blamed.

Paths go to git literally, blame gets a validated full SHA and no
--end-of-options, which git refuses there, and every call has a
two-minute deadline. Caps, deadlines, binary files, symlinks,
submodules, unmapped commits and skipped rename detection become
diagnostics shown with the original on every outcome and in the
report; malformed git output stops the run. This commit only
annotates; nothing is parked yet.
