feat: overcommit suspended VMs' freed capacity (Phase 2 Task 4) - #25
Merged
Conversation
…sk 4) Suspended VMs free their memory to node-local disk, so they no longer occupy schedulable capacity. Exclude VMPhaseSuspended from sumUsedResources and countRunningVMs so the scheduler packs new VMs into the vCPU/RAM freed by suspension. Suspending/Resuming still count (memory resident during transition). Backward-compatible: with no suspended VMs, accounting is unchanged.

Completes the Phase 2 density story: now that VMs can suspend (#24), the scheduler should reclaim their freed resources.
Suspended VMs free their memory to node-local disk, so they no longer consume schedulable capacity. This excludes
VMPhaseSuspendedfromsumUsedResourcesandcountRunningVMs, so the scheduler packs new VMs into the vCPU/RAM freed by suspension — the overcommit that turns "N running VMs" into "N reserved, k resident, k ≪ N".Suspending/Resumingstill count (memory is resident during the transition — conservative, avoids OOM).Test:
countRunningVMsexcludes Suspended while counting Suspending/Resuming.
