[libvirt] [PATCH 0/4] qemu: always use blockdev non-shared storage migration with blockdev (blockdev-add saga)

Posted by Peter Krempa 4 years, 7 months ago

Once we enable blockdev there's no need to stick to drive mirror for
non-shared-storage migration.

This patchset applies on top of the external snapshot branch:
