You mean you have a domain and you want to get list of all its volumes
or vice versa?

There's no API for either though.

For the former you'll have to dump domain XML and iterate over disks to
look up them in libvirt. Just like you do now.
For the latter, there's no easy mapping. But I know virt-manager does it
somehow. /me goes and looks into the code.


So basically it's fetching all the volumes and all domain XMLs and
computing the intersection.
