Get instance block-migration working reliably; script and document
Open, HighPublic


Right now block migration sort of works, but...

  • migrated instances lose their copy-on-write aspects and get huge
  • post-migrated instances can be suspended re-compressed and resumed, but suspend/resume is suspect
  • overprovisioning rules are ignored for live-migration which means we can't actually migrate to an already-partly-full server
