How to enable NUMA on a VMware guest

How to enable NUMA on a VMware guest


Just want to share a bit of insight on VMware - after spending to much time on finding out why-oh-why the vNUMA doesn't appear on my SQL server running on top of VMware.

The trick is to disable "HotAdd CPU" for the VM-guest. Simply.

It is all documented in this hard-to-find KB:
