[Users] VDSM and RHEL problem

Hello, I am running Ovirt 3.1 and everything was running well but then I decided to upgrade to a system with more memory for the engine and now the VDSM version dropped to 3.1 and the RHEL is complaining that there is no compatible pc. This wasnt a problem before and I tried to go back to the old system but now both of them are giving the same error. Anyone have any ideas what I should be looking to fix here? I am not sure if the 2 problems are related, I am running CentOS 6.3, Ovirt 3.1 and using the dreyou builds. Thanks -- Jonathan H Cox
