I have openSUSE 11.3 GNOME desktop instances in VMware ESX... works
great and performance is good.

Do this every day from my openSUSE 11.3/GNOME laptop; accessing openSUSE
11.3/GNOME instance on ESX as well as a Windows Vista instance in local
VMware Workstation.  Works great, performance is good.

I only have CentOS instances as servers (all in VMware ESX... and, of
course, performance is very good).
