virt-devel is in the Code Ready Builder which is PowerTools in CentOS.
The upstream in Code Ready Builder had tooling issues which caused the
virt module to diverge from the virt-devel one so you could not
actually install anything from virt-devel and have a working system
until mid September (from what I can tell in EPEL repo breakouts.) I
am expecting that whatever the tooling issue is also what is causing
problems getting the two to sync up in CentOS also.

It could be.. the virt-devel in Code Ready Builder was not matching
virt module from May until late September until they got whatever
working again..
