This is a known issue with all virtualization solutions. The realtime clocks inside the Virtual Machine jitter quite a bit which causes havoc with the udp media streams. I have never heard of someone using any VoIP product inside a VM and being happy with the result. To the best of my knowledge, all the current VM products suffer from this - Hyper-V, Xen and VMware, VMWare being the worst.
Xen shares access to the system clock with paravirtualized guests directly, so you might find that to be somewhat better than VMWare. More here - http://www.vmware.com/pdf/vmware_timekeeping.pdf The performance of the server is irrelevant. Google for UDP jitter in combination with VMWare.
