Hello Tino,
The version of libvirt is 0.9.8-2ubuntu17.2. It looks like there is a 0.9.13 release from July 2.

It looks like I should be able to build some packages using files here: 

Hopefully I can get to that soon and let you know how it goes.

Thanks for your reply,

Dear Gary,

Which version of libvirt are you using? If possible, please update to
the latest available version on libvirt.org.
