This process needs to be automated as we create and destroy dozens of virtual machines on a nightly basis to test our applications. Our script works fine when installing older OS versions (RHEL 6.2 and prior).  But with recent OS versions (RHEL 6.3), Anaconda installation halts with a warning:

I think that should do it b/c the devices will then have a structure that 
anaconda won't flake out on.
