[libvirt] [PATCH 0/3] qemu: Allow migration with disk cache on

Posted by Jiri Denemark 9 weeks ago
QEMU 4.0.0 and newer automatically drops caches at the end of migration,
which means we can safely allow migration even if disk/driver/@cache is
not none nor directsync.

Jiri Denemark (3):
  qemu: Clarify error message in qemuMigrationSrcIsSafe
  qemu: Check for drop-cache capability
  qemu: Allow migration with disk cache on
