I don't think this is the right level of granularity because
you really want control over individual disks to be removed,
the disctinction of whether a disk is from a storage pool or
not is not relevant to the task at hand.
eg, Consider a VM with 4 disks in the config, sda, sdb, sdc and sdd
and you want to delete sda and sdc, but not sdb since that it on iSCSI
which we can't remote delete, and not sdd since that's a data disk we
want to keep for a future VM.
virsh undefine foo --remove-disks=sda,sdc
Or delete all writable disks:
virsh undefine foo --remove-disks
It would be best if virsh would print a confirmation for each disk
removed, so the admin knows whether it succeeded or not
# virsh undefine foo --remove-disk-names=sda,sdc
Deleted disk /path/to/disk/for/sda
Failed to delete disk /path/to/disk/for/sdc
# virsh undefine foo --remove-disk-names=sda,sdc
Deleted disk /path/to/disk/for/sda
Deleted disk /path/to/disk/for/sdc
Undefined VM foo
