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.
