VMware Vsphere allows config changes without rebooting the guest!!!

Not exactly. Well, it only works if you have MS windows 2008 server.
I tried to increase the memory on a server running windows 2003 enterprise. The memory option was greyed out. What the heck.

Hey Vmware, tell me that next time you post on the fly changes to guess on vsphere...ESX4
