He has expressed concerns that if oVirt curates the qemu package in order to have the snapshotting flag turned on, then there might arise a situation where each project within the SIG would be getting their own versions of qemu.

Upon discussion with Douglas Landsgraf and Itamar, it seemed to make more sense to keep downloading from CentOS repo and rebuilding it with flag enabled and either sharing that with the SIG or inside our own oVirt repository.

If we were willing to take on such a responsibility for the SIG, then this would mitigate multiple versions of qemu appearing.

Personally I wonder why it's that important. With RHEL7 out and CentOS7
expected soonish, why not aim at supporting that. I'm sure that qemu is
new enough to support snapshots.
