Apart from all the licensing issues etc, I know by experience that some Oracle products run on VMWare very well, but other DO have problems (at least on VMWare Workstation, not sure about ESX) Oracle 10g Application Server Infrastructure for example causes masses of Page Faults, and keeps using 5 to 10% CPU while doing nothing (except page faults). It's a known issue, but right: unsupported, so.....

But under ESX we have seen different behaviour as well. Configs running perfectly under 'real iron' started to show faulty behaviour when ported to VM. (In this case, Win2003 server).

So you may be replacing one problem with an other.....
