That’s so cool. I have Fusion and XP but haven’t installed them yet. It’s that very ability, multiple OS, that made the decision to buy a new Intel Mac so much easier. I do graphics work, mostly pre-press, and there’s a lot of bad Publisher stuff that I get. My job is to get it out of whatever program it was created in and get it into the appropriate Adobe program and prepare it for press. The perfect scenario for a dual system.
I’m impressed that you’re using so many systems. What Mac are you running them all on?
At the moment I'm using my 2.16GHz/2GB/120GB MacBook, with the WinXP VM doing some Win-only tasks while I FReep in OS-X-land. I had my Vista VM running earlier to chase a bug one of my users reported, and cranked up Fedora to try something out earlier tonight also.
My Mac Mini has all the above, plus NetBSD (so I can model and prototype my network changes before taking them live), as well as Win2K, Win98, and MSDOS.
I don't run them all at once, of course -- I could, in theory, but there's no screaming reason to, since I typically only bring them up to do specific tasks. And frankly the Vista VM really wants at least 1GB of RAM all by itself, so with only 2GB total RAM, I don't generally run more than 2 VMs at a time over OS-X.
I suppose if I had a bigger machine (MacPro, whatever) with tons of RAM, I could run 'em all at once, but I live off-grid (PV power only) and so small is beautiful.
