Subject: [PATCH] qemu: Fix value of 'device' argument for blockdev-mirror

d76c62
When using blockdev configurations the 'device' argument of
d76c62
'blockdev-mirror' must correspond to the topmost node in the block node
d76c62
graph. Libvirt didn't do this properly in case when 'copy_on_read'
d76c62
option was enabled on the disk.
d76c62
d76c62
Use qemuDomainDiskGetTopNodename to fix it for the blockdev-mirror calls
d76c62
in qemuDomainBlockCopy and the non-shared-storage migration.
