[Pkg-libvirt-maintainers] Bug#1029334: virsh vol-delete stumbles over lost logical volume

[Harald Dunkel]

Package: libvirt-clients
Version: 7.0.0-3

If a logical volume has been deleted or renamed without the help
of virsh, then virsh vol-delete dies with an internal error later.
Sample:

root at srvl030:~# lvs

root at srvl030:~# lvcreate -n rr03a.vda.lv -L1G storage
   Logical volume "rr03a.vda.lv" created.

Vol rr03a.vda.lv deleted


Should be easy to avoid. Regards
