We have a Grid environment running on a VM on an ESX server and have for a couple years. We have a copy of the VM in our DR site so we can bring it up in case of a disaster. The only issue we've run into is the DR copy. I activated it once and every morning around 2am, the OC4J_EM process would consume 100% CPU and die. It turns out that our 100 Windows VMs all do their virus scanning at the exact same time. Before I figured out the virus scanner, I had a SR open with Oracle. They had me upgrade to and it didn't change anything. I applied a patch and also upgraded to 11g. Then it was a different process which pegged the CPU and died but the end result was the same.
