Lifecycle

IMP provides snapshot-based lifecycle primitives for save/restore and fast VM provisioning.

Sections

• Snapshot
• Warm Pool

Concepts

• ImpVMSnapshot: captures a running VM's memory and disk state. Supports one-shot and scheduled recurring captures.
• ImpWarmPool: keeps a pool of pre-booted VMs ready for instant assignment. Pool members boot from an elected snapshot base.

Warm pools are the recommended path for latency-sensitive workloads — VMs are booted and waiting before they are needed.

Runtime and Pressure Handling

• imp-runtime uses updateStrategy: OnDelete — it never rolls automatically. See Day 0 — Runtime OnDelete for cordon/drain and delete-pod rollout.
• pressureLifecycle.enabled is false by default (opt-in). When enabled, the operator suspends largest VMs first on MemoryPressure and never auto-resumes. See Day 0 — pressureLifecycle and Architecture — Operational Notes.
