I'm a bit of a noob when it comes to virtualization and the WMware website seems kind of vague about the capabilities of their free player product. I gather that WMware Server (which is free) is no longer supported and required a Server host OS to begin with. I'm just wondering if what I'm planning to do is possible and/or a good idea. I have a small home server running a celeron G540 with H61 chipset, 8GB ram. What I'd like to do is: Install XP x64 as host OS Then install VMWare Player with Windows 2003 Server as a guest OS running WSUS And possibly one other Windows or Linux OS as a guest in the future but no immediate plans for that. Later I might want to run Windows 2008 Server but no immediate plans for that. Are there any networking considerations I'm not aware of? I'll probably store the WSUS data on the host OS and setup a network share since I feel that would be easier to backup.
