If anyone figures this out please post it to this thread. I am working on a wiki page for the VMWare appliance and I would like to be able to inform people on how to handle this situation.
I had some issues under vmware fusion. They were resolved by adding clock=pit [1] to the kernel boot params and switching to host-only networking, and running natd + ipfw on the host system. The vmware natd would probably also work. haven't tried myself. The clock=pit is the big kicker. Also, recompiling the kernel with HZ=100 might help to reduce the load on the host system. [2] Though, with a small number of vms/vcpus on decent hw the number of context switches probably won't have much of an effect.

Also, IIUC, those running VMWare Fusion on Macs are not experiencing this, correct? What about those using a hypervisor like ESXi? Any known issues?
Thanks, MC

Hello Ken, hello all,
I just read about the FreeSWITCH VMware applicance. I'm curious about your experiences with the audio quality on VMWare, so here's a new thread.
I've installed freeswitch on VMware Server for Windows. The IVR audio always plays choppy, while the server itself has no performance issues. The same poor voice quality also goes for Asterisk or Yate, even on a very fast VMware ESX system.
Did you experience the same and/or do you have pointers on how to troubleshoot and fix this?
There is a high resolution timer you need to enable on vmware... I'm not familiar enuff with all the versions of vmware to advise there that switch is, but they have a couple of articles on it in their knowledge base
