Bug Description

Hyper-V can change the order of the mounted drives when rebooting a host and thus passthrough disks can be assigned to the wrong instance resulting in a critical scenario.

this is not critical from a nova point of view (though it may be for hyper-v). The priorities should be overall project prio, not individual driver prio

    Fixes Hyper-V volume mapping issue on reboot

    Hyper-V does not manage iSCSI mounted passthrough disks
    correctly on reboot in some circumstances where disk
    number assignment can change, resulting in instances potentially
    booting with the wrong volume attached.
