We aren't quite forcing people to move to newer versions. Only those
installing nova test-requirements need newer libvirt. This does not
include people using eg devstack. I think it is reasonable to expect
people testing tip of nova master to have a reasonably newish test bed
to test it (its not like the Infra team moves at a really fast pace :)
).

Avoiding system site packages in virtualenvs is a huge win particularly
for consistency of test results. It avoids pollution of site packages
that can happen differently across test machines. This particular type
of inconsistency has been the cause of the previously mentioned
headaches.
