This change adds a libvirt command to list all instance UUIDs with hw_machine_type unset in their image metadata. This will be useful to operators attempting to change the [libvirt]hw_machine_type default in the future as it allows them to confirm if it is safe to change the configurable without impacting existing instances. blueprint: libvirt-default-machine-type Change-Id: I39909ace97f62e87f326d4d822d4e4c391445765
