Agree with Itamar.  I'd also consider having a vm or 2 that are running
various target distros where we can build packages for different
distros.

Also, 200GB disk seems a bit excessive to me.  Since this is running on
oVirt, maybe a thin provisioned disk would be a good choice.  The slaves
generally don't need as much disk.
