The CentOS 7.3 release updated to libvirt 2.0,  which is now taking
precedence over the previous virt sig libvirt packages (which were
1.3).

I've pulled in the changes from Fedora 25, which uses libvirt 2.2.0.
I've built and tested them for CentOS 7 and they work for me.  (I'm
having some infrastructure issue testing C6.)

Please test them if you have an opportunity.  I'll leave them there
for a week and then push them to release if I don't have any
complaints.

Thanks,
 -George
