Lanny I was told that for any kind of performance, at least 1G of memory per VM plus 1G for the host was "a good idea." that was why I originally upgraded mine to 2G (well, that and I *really* wanted a better CPU, and this was a great excuse). That might have been for VMWare Workstation (not free, but I had it at work) not VMWare Server (which I use at home). When I had 2G, I only allowed my VM WXP guest to use 768M, but I upped that to 1G when I replaced my 2G with 4G. I also have a CentOS 5.? guest on the same box, but I've never actually tried running them both at the same time. HTH. mhr
