Public bug reported:

There are several ways of selecting the disk_bus for a BDM. One of them
is using the hw_disk_bus image property which, if present, is inherited
by volumes created from an image.

When booting from a volume that has this property defined, even though
we might think it will be considered when selecting the bus, it is
ignored because the code that guesses the bus and device name for volume
BDMs expects it to be defined in the same BDM.
