Increasing CPu?

[lsulax]

I thought in Vsphere 4.1 ESX that the virtual machine can increase the # of CPu's while the vm is powered on?

The guest OS is W2008 R2 server.same thing for a 2003 r2 or 2000 server

[lsulax]

it is grayed out on all of our vm's?

Hello.

AFAIK, Windows 2008 DC Edition and Windows 2008 R2 DC Edition support adding CPU and then being able to immediately use them. Windows 2008 x64 STD and ENT can hot add, but must be rebooted for Windows to use them.

Good Luck!

Remember for hot plug to work, you also have to configure it on the guest while it's powered down and your guest must be at vHardware 7. Edit SettingsOptionsMemory/CPU hotplug. We do this on our templates were applicable.

Below is a good chart

figured it out it is disabled under the options tab

I dont think you can increase #CPUs when VMs are powered on.

To do this you need to poweroff VMs.

>>> Ignore this post, I was thinking other aspect without hot-adding CPUs.
