Get as much RAM (at least 2GB, more than 2GB would imply you'll run a 64b OS as the host) and hd-space as you can, and use preferrably Raid0 on the ones you get. You'll appreciate the speed with the VMs. I run VMWare server at work on a amd x2 4400 under WinXP x64 and the same thing at home on regular 32b WinXP. That is to say, same hw at home as at work, and I don't see any performance pros or cons running VMWare server on 32 or 64b hw. _____ From: windows2000-bounce@xxxxxxxxxxxxx [mailto:windows2000-bounce@xxxxxxxxxxxxx] On Behalf Of Ray Costanzo Sent: Wednesday, November 28, 2007 5:11 AM To: windows2000@xxxxxxxxxxxxx Subject: [windows2000] 32-bit virtual machines Hi list, My winter project this year is to rebuild my home network. I'm upgrading to a WS2003 domain from Windows 2000 (or I may venture into 2008 depending on when that comes out). I'm going to make use of virtualization as much as possible and anticipate having five or six VMs. I'm not a big fan of 64 bit OSes, so I want to run all 32 bit ones. When I build the machine that will host all the virtual machines, I'll want to get as much processing power as I can reasonably afford. It seems, however, that all the hardcore processors these days are 64 bit. Will this matter? Will I just be wasting money buying a 64 bit processor for all 32 bit OSes? Aside from the "you should run 64 bit OSes" responses, any thoughts on this? Thanks
