Hi Vang and All.

I build this rpm's for testing oVirt in CentOS 6.2, and it's working in my test environment.

Today, I checked engine installation on fresh (but updated)  CentOs 6.2 without problem.

You can try to cleanup ovirt (engine-cleanup) remove all ovirt, vdsm and jboss packages (yum remove ovirt* vdsm* jboss*) clean yum cache and install ovirt-engine again.
