You'll almost certainly be much happier getting VMware. The Essentials pack (three servers at 2 CPUs each) lists for $560, . There will be even less overhead than in Ubuntu, better support, probably better compatibility.
You'll want at least 16GB of RAM, and when people realize how easy and cheap it is to spin up VMs they will do it; you might want to get 32GB just to be safe in the future. Ditto for CPUs, though the Essentials license limits you to two CPUs per host. (You can get 6 or 8 cores per CPU, though; unless these are very high load servers, or multi-core servers, having 12-16 cores on a host is likely more than adequate.) If you have a bit more budget, get a couple servers and shared storage, so you can do fun things like vMotion (moving your guests between host servers without having to shut them down first). You can probably get by with "cheap" shared storage like a Dell PowerVault NAS, unless you have really high IO requirements. If you're new to virtualization, it's worthwhile to talk to a VMware expert.

I am doing this right now with two HP DL-160 G5. Stupid HP has some weird Memory configurations. Anyway those two HPs sound like Jet engines although they are in our NOC I don't hear them. This server will be running Ubuntu 12.04 LTS with the latest Virtual box software. It will hold 17 to 20 SCO legacy systems who will get 512mb of RAM apiece. They are character based without the X system running and the sessions on there are just Telnet (well ssh) but still very low overhead. We normally buy HP or Dell (whoever has the best bang for the buck. Any pointers are greatly appreciated. Please no flames that I am keeping SCO machines around. I know about them but you have to play with the cards that are dealt you. -- John J.
