During live migration disk devices are updated with the latest
block device mapping information for volumes. Previously this
relied on libvirt to assign addresses in order after the already
assigned devices like the root disk had been accounted for. In
the latest libvirt the unassigned devices are allocated first which
makes the root disk address double allocated causing the migration to
fail. A running instance should never have the hardware addresses
of its disks changed mid flight. While disk address changes during
live migration produce fatal errors for the operator it would likely
cause errors inside the instance and unexpected behavior if the device
addresses change during cold migrationt review. With this disk addresses are no
longer updated with block device mapping information while every
other element of the disk definition for a volume is updated.
