I feel so dirty. I am using vmworkstation because at the time I wanted to
learn Linux server things, not vm things. Now I am looking at Xen and it
seems interesting. However, I am having a hard time on finding good info (I
admit, I am not putting in hours of research, just 20 min here and there when
the thought strikes me). I I have really found so far is this:

http://julien.danjou.info/xen.html ignore the "not maintained" message, the
guy updated it enough to still be relevant. I have not found anything yet to
tell me how to set up "host only" networking.

I want one VM to act as a router like this:

WAN<--eth0 192.168.200.15/24-->dom0 <---eth1--192.168.200.16/24->domU<---virt
ethX--192.168.1.16/24--->other domUs

there is information about this on the shorewall website:
http://www.shorewall.net/XenMyWay.html, though it's extremely
complicated and likely more than you need. It got me started
though. Combined with pciback(see Xen wiki for info) to move my
red-zone interface to my domU firewall, it works pretty well. I have

WAN <- physical eth0 moved to domU (firewall) with pciback
eth1 in firewall domU 192.168.2.1<- DMZ domUs (mail, web, etc)
eth2 in f/w domU 192.168.1.1<- dom0 fileserver and LAN

The whole thing is a little dodgy, and seems kind of fragile. It
doesn't always work well on a reboot, as I don't seem to have the
interfaces coming up in the right order, but it does work.
