Hi
I know this is NOT best-practice, but we are working with Microsoft to troubleshoot a performance issue at a client, and one of the troubleshooting steps is to dedicate a CPU core/socket/vcpu to a particular VM.  The host the VM is running on is not oversubscribed, and while I know it's possible to set "CPU Affinity" to lock a VM to a particular core (or multiple logical cores), I don't believe setting CPU affinity on one VM prevents other VMs from using the same core.  We want to isolate a VM to a particular core and not allow other VMs to use it.

Again, I realize this is not best practice, and would not be a long-term solution, but for troubleshooting it is something we need to attempt.

Is there a way to do this?
