Marcus Sorensen commented on CLOUDSTACK-4012:
---------------------------------------------
Thanks, I would hope we are targeting RHEL 6.4 as the primary redhat OS for
4.2, but we need to support the least common denominator (ubuntu 12.04 is
probably the oldest we support). I just backed out that change, and will
hopefully reapply it sometime in the future when everyone is shipping a more
recent libvirt.
