Subject: [PATCH] qemu: Fix value of 'device' argument for blockdev-mirror
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8
|
|
Content-Transfer-Encoding: 8bit
|
|
|
|
When using blockdev configurations the 'device' argument of
|
|
'blockdev-mirror' must correspond to the topmost node in the block node
|
|
graph. Libvirt didn't do this properly in case when 'copy_on_read'
|
|
option was enabled on the disk.
|
|
|
|
Use qemuDomainDiskGetTopNodename to fix it for the blockdev-mirror calls
|
|
in qemuDomainBlockCopy and the non-shared-storage migration.
