- Created T026-practical-test task.yaml for MVP smoke testing - Added k8shost-server to flake.nix (packages, apps, overlays) - Staged all workspace directories for nix flake build - Updated flake.nix shellHook to include k8shost Resolves: T026.S1 blocker (R8 - nix submodule visibility)

name: PlasmaVMC Feature Deepening
|
|
status: complete
|
|
goal: Make KvmBackend functional - actual VM lifecycle, not stubs
|
|
priority: P0
|
|
owner: peerA (strategy) + peerB (implementation)
|
|
created: 2025-12-08
|
|
|
|
context: |
|
|
Scaffold complete (5 crates) but KvmBackend methods are stubs returning errors.
|
|
Spec defines 10 crates, but depth > breadth at this stage.
|
|
Focus: Make one hypervisor backend (KVM) actually work.
|
|
|
|
acceptance:
|
|
- KvmBackend.create() spawns QEMU process
|
|
- KvmBackend.status() returns actual VM state
|
|
- KvmBackend.start()/stop() work via QMP
|
|
- At least one integration test with real QEMU
|
|
- plasmavmc-server can manage a VM lifecycle end-to-end
|
|
|
|
## Gap Analysis (current vs spec)
|
|
# Existing: plasmavmc-types, hypervisor, kvm, api, server
|
|
# Missing: client, core, firecracker, mvisor, agent, storage (defer)
|
|
# Strategy: Deepen existing before expanding
|
|
|
|
steps:
|
|
- step: S1
|
|
action: Add QMP client library to plasmavmc-kvm
|
|
priority: P0
|
|
status: complete
|
|
owner: peerB
|
|
notes: |
|
|
QMP = QEMU Machine Protocol (JSON over Unix socket)
|
|
Use qapi-rs or custom implementation
|
|
Essential for VM control commands
|
|
deliverables:
|
|
- QmpClient struct with connect(), command(), query_status()
|
|
- Unit tests with mock socket
|
|
|
|
- step: S2
|
|
action: Implement KvmBackend.create() with QEMU spawning
|
|
priority: P0
|
|
status: complete
|
|
owner: peerB
|
|
notes: |
|
|
Generate QEMU command line from VmSpec
|
|
Create runtime directory (/var/run/plasmavmc/kvm/{vm_id}/)
|
|
Spawn QEMU process with QMP socket
|
|
Return VmHandle with PID and socket path
|
|
deliverables:
|
|
- Working create() returning VmHandle
|
|
- QEMU command line builder
|
|
- Runtime directory management
|
|
|
|
- step: S3
|
|
action: Implement KvmBackend.status() via QMP query
|
|
priority: P0
|
|
status: complete
|
|
owner: peerB
|
|
notes: |
|
|
query-status QMP command
|
|
Map QEMU states to VmStatus enum
|
|
deliverables:
|
|
- Working status() returning VmStatus
|
|
- State mapping (running, paused, shutdown)
|
|
|
|
- step: S4
|
|
action: Implement KvmBackend.start()/stop()/kill()
|
|
priority: P0
|
|
status: complete
|
|
owner: peerB
|
|
notes: |
|
|
start: cont QMP command
|
|
stop: system_powerdown QMP + timeout + sigkill
|
|
kill: quit QMP command or SIGKILL
|
|
deliverables:
|
|
- Working start/stop/kill lifecycle
|
|
- Graceful shutdown with timeout
|
|
|
|
- step: S5
|
|
action: Integration test with real QEMU
|
|
priority: P1
|
|
status: complete
|
|
owner: peerB
|
|
notes: |
|
|
Requires QEMU installed (test skip if not available)
|
|
Use cirros or minimal Linux image
|
|
Full lifecycle: create → start → status → stop → delete
|
|
deliverables:
|
|
- Integration test (may be #[ignore] for CI)
|
|
- Test image management
|
|
|
|
- step: S6
|
|
action: Wire gRPC service to functional backend
|
|
priority: P1
|
|
status: complete
|
|
owner: peerB
|
|
notes: |
|
|
plasmavmc-api VmService implementation
|
|
CreateVm, StartVm, StopVm, GetVm handlers
|
|
Error mapping to gRPC status codes
|
|
deliverables:
|
|
- Working gRPC endpoints
|
|
- End-to-end test via grpcurl

|
Foreman recommended PlasmaVMC deepening as T011 focus.
|
|
Core differentiator: Multi-hypervisor abstraction actually working.

S1-S4 are P0 (core functionality), S5-S6 are P1 (integration).
