refactor(vmm): improve crash diagnostics and kernel cmdline handling by DorianZheng · Pull Request #227 · boxlite-ai/boxlite

DorianZheng · 2026-02-11T07:49:19Z

Summary

Fix Box fails to start when passing my host env vars:Timeout waiting for guest ready (30s) #222
Add ExitInfo enum for JSON crash data transfer between shim and library
Add CrashReport struct for user-friendly error message formatting
Add GuestEntrypointBuilder for managing env vars within kernel cmdline limits
Refactor shim.rs to shim/main.rs + crash_capture.rs directory structure
Fix LIBKRUN_CMDLINE_FIXED_OVERHEAD constant (300 bytes)
Preserve diagnostic files on crash (don't cleanup box directory)
Improve build script with deterministic OUT_DIR detection

Architecture

Crash Diagnostics:

ExitInfo (vmm layer): Pure data structure for JSON serialization - shim writes, library reads
CrashReport (litebox layer): Presentation/formatting for user-friendly error messages

Kernel Cmdline:

GuestEntrypointBuilder: Manages env vars with FILO semantics within arch-specific limits (2KB ARM64, 64KB x86_64)

Files Changed

New Files	Purpose
`vmm/exit_info.rs`	ExitInfo enum for JSON crash data
`litebox/crash_report.rs`	CrashReport for user-friendly errors
`bin/shim/crash_capture.rs`	Panic/signal handlers
`init/tasks/guest_entrypoint.rs`	GuestEntrypointBuilder

Test plan

cargo test -p boxlite --lib -- vmm::exit_info (5 tests)
cargo test -p boxlite --lib -- litebox::crash_report (4 tests)
cargo clippy -p boxlite --lib (no warnings)
cargo fmt --check (clean)

- Add ExitInfo enum (vmm/exit_info.rs) for JSON crash data transfer between shim and library (signal/panic variants with serde) - Add CrashReport struct (litebox/crash_report.rs) for user-friendly error message formatting with context-aware troubleshooting hints - Refactor shim.rs to shim/main.rs + crash_capture.rs directory structure - Extract CrashCapture to handle panic hooks and signal handlers - Fix LIBKRUN_CMDLINE_FIXED_OVERHEAD constant (300 bytes) - Move is_printable_ascii to util module - Update guest_connect to use CrashReport for crash detection Improves crash diagnostics by separating data (ExitInfo) from presentation (CrashReport), enabling better error messages when VM startup fails.

@shayne-snap @uran0sH Can you take a look?

Sorry for the late reply.

I tested the main branch on my laptop, I saw 2026-02-12T00:52:22.666558Z WARN boxlite::litebox::init::tasks::guest_entrypoint: Skipping env var: kernel cmdline size limit reached env_key=_CE_M env_value=*** total_size=1536 var_size=9 limit=1539 which is great, BUT still encountered an error.

console.log is empty.

Hi @shayne-snap. So sorry for the inconvenience, please run another test

rm -rf ~/.boxlite/images/disk-images/
rm -rf ~/.boxlite/tmp/
make clean
make dev:node
node simplebox.js

The current error message is still not good for diagnosing issues. I will keep on improving it

Hi @shayne-snap. I have spent some time optimizing the error message a little bit #240. Can you update to the latest code and try above command again

Hi. Sorry for the late reply. It took a while to redownload everything(I have to use VPN). I updated to the latest code, and ran the commands to remove the old stuff. Here's the output down below:

    refactor(crash): extract ProcessMonitor and improve crash diagnostics (#240)

    - Add ProcessMonitor abstraction for waitpid-based process liveness detection
    - Capture stderr to file BEFORE subprocess spawn (catches pre-main dyld errors)
    - Pass BoxFilesystemLayout through spawn chain (DRY - no redundant recreation)
    - Remove stderr from ExitInfo::Signal (CrashReport reads directly from file)
    - Simplify CrashCapture::install() to only take exit_file parameter

    The ProcessMonitor encapsulates the Unix parent/child constraint for waitpid,
    handling both owned (spawned) and attached (reconnected) process modes with
    explicit ProcessExit::Code vs ProcessExit::Unknown return types.

Got it. Let me check

I accidentally passed process.env to Node SDK by SimpleBox

Actually, Most developers and me dont need to pass the whole process.env. The normal SimpleBox.js example(without process.env) works on my laptop. It was an accidental test.

@shayne-snap Would you mind using a binary search approach to isolate which environment introduced this issue?
According to the report, boxlite-shim exits silently with exit_code = 0, which seems unusual. I’m not sure where to start🥲—any help would be appreciated.

shayne-snap · 2026-02-12T09:56:13Z

@DorianZheng Given that this pull request have already fixed the env vars number is too big issue and the solution works both for you and @uran0sH . It's a low priority task. We can fix it later.

I'll try to explore the root cause on my computer and ask for help when I need. How about that?

Sounds perfect! Thanks again for all the testing. Ping me in the future whenever you find anything 🥰
