Public bug reported:
While trying to add multiple disks to ubuntu guest on an ubuntu KVM, the
following error is reported.
Error: internal error: process exited while connecting to monitor:
qemu-system-ppc64: -drive
file=/dev/sdd,format=raw,if=none,id=drive-scsi0-0-0-0,cache=none,aio=native:
Duplicate ID 'drive-scsi0-0-0-0' for drive
It seems libvirt is using the same id for more than one disk. My
impression is that something is wrong with the libvirt being used in
Ubuntu 16.04.x.
The target device parsing logic which generates the device alias has
gone wrong as the XML used has the target dev names given in unusual
format as vd2, vd3 where usual nomenclature is to have
/^[fhv]d[a-z]+[0-9]*$/.
The following regex should be followed while assigning the disk name: (regex)
/^[fhv]d[a-z]+[0-9]*$/
However, note that any trailing string of digits is simply ignored by libvirt.
A patch has been sent upstream.
The patch has been accepted upstream. commit 5729746.
