Unfortunately not - I was building libvirt from git (in case it needed
any changes).  We're missing quite a few packages before libvirt can
be built from the RPM, see these files (although they are a bit out of
date):

As new packages get built for Fedora 25, we are picking them up
automatically and trying to build them for RISC-V:

QA-ing the whole thing, beyond simple testing by hand, is quite
difficult especially without solid hardware.
