What's really weird is that one Xymon server that I run on VMWare Server on X86 has a clock that actually gains time! Bizarre.

I have a 4.2 install of Hobbit up and running and I am very happy with it. It runs on an old Gateway workstation with a Celeron and 512MB and performs stellar! CentOs 5 nothing fancy. I was going to move it to a more recent piece of hardware a Dell OptiPlex 320, which at least it is under warranty. I had the Idea of running it as a Xen VM on a Debian host. Is this a bad idea?
The only problem I've seen with Hobbit running in a VM is that the virtual machines - at least with VMware - sometimes have problems maintaining their system clock in sync with the real world. The clock tends to drift somewhat.
Since lots of stuff in Xymon (Hobbit) is timing dependant, this can be a problem. The 4.2.0 and 4.2.2 versions in particular would not handle a system clock going backwards very well - 4.2.3 is better, and it should be all cured with 4.3.0, at least so that Xymon doesn't crash if that happens. But it will still affect the timestamps that appear on all of the log entries Xymon makes.

What VM software do you use ? I often seen VMWare guests having troubles with clock management. The issue was solved with a kernel parameter (didn't remember wich one).
