When looking up storage volumes virsh uses multiple lookup steps.
Some
of the steps don't require a pool name specified. This resulted into a
possibility that a volume would be part of a different pool than the
user specified:
Let's have a /var/lib/libvirt/images/test.qcow image in the 'default'
pool and a second pool 'emptypool':
Currently we'd return:
$ virsh vol-info --pool emptypool /var/lib/libvirt/images/test.qcow
Name: test.qcow
Type: file
Capacity: 100.00 MiB
Allocation: 212.00 KiB
I believed that the --pool parameter for vol-info (and *some* others)
was only a hint in case you had more volumes with the same name
(specifying absolute path with a pool doesn't make any sense). That
would mean the BZ is notabug actually, but let's assume such users
exist...
After the fix:
$ tools/virsh vol-info --pool emptypool /var/lib/libvirt/images/test.qcow
error: Requested volume '/var/lib/libvirt/images/test.qcow' found in a different
pool (default) than specified
I'd say this is rather noisy. How about changing it to ...'%s' not
found in pool '%s'... or "is not in pool '%s'?
ACK after release with or without the change mentioned above.
