I don't want MS crap on my OS X (need that for work=20 ATM), and I can't imagine they've ported it to Linux. I have no reason=20 to boot Windows except for games, and if I was going to do that, I may=20 as well shrink my Windows partition to make room for a native install. Which would be fine, but it's a lot of work when I don't run Ubuntu=20 normally. I'd be willing to test on the one Ubuntu server I run, but it's across=20 the country until next week, and also work-critical. >> Not to nitpick, but isn't that emulation?

Virtualization splits up the real hardware. It's like a scheduler, only=20 for OSes. Emulation is more like an interpreter -- it reads each=20 instruction and then executes something that does the same thing.=20 Emulation can work from any arch to any arch, so Rosetta (allowing PPC=20 OS X apps to run on OS X86) is emulation. Emulation is usually at least 2x slower than native. Virtualization=20 usually approaches native for CPU stuff, but at least disk IO and=20 graphics usually have to be emulated -- so no 3D acceleration, so no=20 games under a guest OS. If MS wanted to do the best possible thing for their consumers, they'd=20 give you a free XP under VirtualPC with Vista, and actually do=20 virtualization. If M$ wanted to make it even more likely for people to=20 want to upgrade to Vista, they might deliberately make it cost tons of=20 money and make it emulation, so that XP looks slower, and native Vista=20 apps look so much faster that people complain until everything works on=20 Vista. > If Virtual PC is emulation, maybe Virtual Server 2005 R2 (also free of > charge) is virtualizaton. I have no idea what Virtual Server is.
