Hi Neil,

Sorry for the delay, the places I would suggest to get in touch with Libvirt folks are:

* Mailing list: https://www.redhat.com/mailman/listinfo/libvirt-users
* IRC: #virt on irc.oftc.net (often quite slow but stick around and someone will try help, lots of lurkers)
* Bugzilla: https://bugzilla.redhat.com/enter_bug.cgi?product=Virtualization%20Tools

Hope that helps,

Steve
