I have an existing windows 7 x64 enterprise guest that I'd like to add more CPU cores to. I've followed the document from http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1010184 and set the amount of cores to 2. Right now I have a single vcpu, so I would expect to see two graphs in task manager, but I don't. I only have one. Also, device manager shows one cpu, and when I run wmic > cpu, I confirm that NumberOfCores is 1.
I've triple checked to make sure that I've spelled cpuid.coresPerSocket is spelled correctly and everything else. Any idea why is seems these extra cores won't enable in the guest OS?
ESX 4.1.0 502767
Windows 7 Enterprise x64 SP1
(also tried on Windows XP Pro SP3)
Thanks!
