Summary

hypeman 0.1.0 ships a faster, more observable runtime for snapshot-heavy workloads.

faster forks and restores

  • UFFD snapshot paging for initial fork restores
  • improved Firecracker fork concurrency
  • parallelized and optimized restore network setup
  • faster standby through diff snapshot reuse and reflink cloning

stronger lifecycle management

  • instance health checks and restart policies
  • auto-standby, scheduled snapshots, and retention cleanup
  • idempotent lifecycle transitions
  • waitForState for blocking state changes

better production visibility

  • always-on metrics
  • per-phase instance timings
  • restore network telemetry
  • lifecycle, hypervisor, and guest exec tracing
  • disk, capacity, latency, and age metrics

cleaner networking and resource control

  • burst-proof admission control
  • active memory reclaim
  • bandwidth reservation fixes
  • TAP cleanup and tc class collision fixes
  • optional egress MITM proxy support

platform updates

  • Cloud Hypervisor v51.1 support
  • image-label kernel selection
  • auto-pull images on instance create
  • OCI cache garbage collection
  • scoped API key permissions and tags

overall: faster restores, fewer lifecycle edge cases, and much better visibility into what hypeman is doing in production.
