But as suggested you are probably best to just add the extra CPU to it and leave it like that, unless you only have 2 single core CPUs in your host or the CPUs are heavily used. A VM configured for 2 CPUs will have to wait for 2 CPU cores to be available before it can do any processing so on heavily loaded hosts adding a CPU can slow the VM down. However with todays multi-core CPUs this is less of an issue than it was years ago.
Our hosts are dual quad-core but two of them do not have hyperthreading.
I'd move the VM to the host that does have hyperthreading.
Thank you, Tom
