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

Posted by Jiri Denemark 17 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
