I really wanted to test under Snow Leopard under one virtualized machine Windows 7, for testing purpose only to see the last operating system from Windows, on my MSI EX600 laptop, but unfortunetly for Parallels Desktop 5 it could not be installed because it does some verification about processor possibility to do virtualisation, mine isn’t able, so with Parallels Desktop 4 i remember i did installed windows xp, i did installed with use of Pacifist 2.6.3 that is compatible with Mac OS X 10.6 “Snow Leopard”, but creating a new machine was doing same errors.
VMware Fusion 3.0 for Mac did the job, i finally installed Windows 7, audio ok, network ok, well it’s nice.i recomand it, and no Vista … there are some great effects in Aero from Windows 7, did not have the time do see the compatibility with another programs, but it’s a good start for the new OS from Microsoft,VMware Fusion 3.0 seems reliable also on old machine like my laptop(Core 2 Duo 1,6G).
