Subject: [PATCH] qemu: Fix value of 'device' argument for block-commit
|

|
|
When using blockdev configurations the 'device' argument of
|
||
|
|
'blockdev-commit' 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 when calling block-commit.
