This would also kill off RHEL/CentOS 7.1 support but that would also seem to be OK at this point.

I've added the details I have for Fedora 25 and RHEL/CentOS 7.3, TL;DR:

Fedora 25:
Libvirt 2.2.0
Qemu 2.7.1
Libguestfs 1.34.3

RHEL 7.3:
Libvirt 2.0.0
Qemu 2.6.0
Libguestfs 1.32.7

I just play someone intelligent on TV so adding Sahid and Vladik who might be better placed to comment in Dan's absence.
