[Libguestfs] [PATCH v5 5/7] v2v: -o libvirt: switch away from virsh
Now that we have a proper libvirt connection object, use it directly to
refresh the storage pool, and define the final guest. This avoids
spawning a new virsh process twice, with no possibility to even share a
possible authentication required.
