There are two other issues I've not managed to pinpoint yet.
- The mouse/keyboard don't seem to function during any virt installs
Maybe https://bugzilla.redhat.com/show_bug.cgi?id=566948
- Unable to login as root after install -- nirik indicated this may also be SELinux related
Sounds similar to https://bugzilla.redhat.com/show_bug.cgi?id=566979
