Virtualizing servers

I have decided that with the rising cost of everything, it is time to start reducing the amount of systems I have running in the house. The nature of my work requires me to have several systems for different purposes. On top of that, I have a MythTV system setup throughout the house, plus the personal systems for my lady and I. I think overall, there are at least 5 systems running 24/7 at any given time (which is a lot, to say the least). If I could reduce one or two of them, that would make a nice difference in power and noise.

I am trying to accomplish this using the VMware server product. I didn't look at Xen just because it seemed a lot easier to setup a VMware system, and the tools are more mature. Ironically, I found out that some people have been successful running MythTV backends inside of a Xen VM. Maybe if I'm ambitious enough...

I made up a linux VM to run FC8 that would replace the existing main server in the house. This server provides SSH, web, DHCP and DNS access to the house. The host system is on a fixed IP address, so that should be a problem.

As of today (May 10th), the work on it has been slow, but relatively painless. I need to take a VM snapshot of the base install and then continue migrating the stuff from the other server. I'm also trying to enable IPv6 on the linux systems I have just for the experience.
