By the time Ocata is released, I think it'll be valid to ignore
RHEL-7.1, as we'll already be onto 7.3 at that time.

If we ignore RHEL 7.1, we could go to 1.2.9 which is the min in Jessie.

We should also now consider our minimum QEMU versions. Jessie will have
QEMU 2.1.0,  16.04 LTS will have 2.5.0 and  RHEL 7.2 will have 2.3.0

So that'd suggest a valid QEMU/KVM version of 2.1.0, vs our current
1.5.3 version.
