We run several application servers (10.1.2, 10.1.3, 10.1.4) on VMWare ESX, guest OS is SuSE linux Enterprise Server (SLES) 9.3. So far no problems. Performance *seems* to be ok. Be sure to install VMware tools on each guest, so VMWare can optimize its performance.
I heard there ARE problems if you use db with raw devices combined with the VMWare 'automove' (don't remember the correct term right now). It seems the devices get corrupted once the guest migrates from one server to another. Haven't tried that one myself yet.
