RE: Oracle VM ?

I think that depends on the VM and what you want to load balance. IBM's MicroPartitioning sure seems to quack like a VM to me, and there's some nifty resource balancing that happens behind the scenes. In a past life, I was handed a 4-core AIX MPV server for three Oracle servers. Very interesting setup with some resource twists a DBA wouldn't normally see (e.g. queries over DBLINKs between two virtual servers on the same physical server).

Although I still don't understand the concept of a tenth of a CPU as it would relate to real-world Databases, but that's another topic. :)
