Hi,
I've got a machine (2xDual Core Opteron, Centos 4.4 x86) running VMware Server 1.0.1 with reasonably high context switching (10K+) on the host with little load. It doesn't seem to be effecting guest performance as yet, however I'm finding it a little perpexing. I've been lurking around the forums looking for something similar but to little avail.
There are three guests running on the machine which are dns server and don't do much. Context switching inside the machines is minimal (max 10-50)
Here's a example of the vmstat, free and load average
