vmware - commercial

does the 9x family? And Windows ME?
simics - commercial - does
alpha, mips, sparc and x86, among others. Has trial licenses.
wine - opensource. x86 only?
In dcslib. Unlike most stuff here, it can sometimes run windows apps
without a windows license, but it can sometimes do a better job with
intended to allow running linux/x86 binaries (including wine) on

opensource. x86 only. Has
abandoned supporting closed-source OSes
opensource. Should be able to run x86 binaries on anything include
solaris, irix, tru64. I tried it under redhat and it eventually
toasted my DOS filesystem file, sometime well before Feb 24, 2003. I
was running either FreeDOS or OpenDOS in it.
Xen - Xen is a
virtual machine monitor for x86 that supports execution of multiple
guest operating systems with unprecedented levels of performance and
resource isolation. A port of Linux 2.4 to run on the VMM works well,
and *BSD and XP ports are in progress. Wed Jan 14 07:24:24 PST
2004. Update, Thu Nov 18 14:40:50 PST 2004: Xen has been running at
least one version of *BSD for a while now. Fri Jan 28 12:40:23 PST
2005: A URL

twoostwo runs on
linux and windows, and can host linux, freebsd, windows, and perhaps
others. It has a free 3 month evaluation.

I finally found a chance (reason) to check out qemu, and I'm very
impressed. It's not all that blazing fast, running an i386 guest OS
on an i386 host OS, however, there's a non-opensource accelerator
module that is supposed to help with that, and without that
accelerator, the emulation appears to be flawless so far. I've used
it to boot a DragonFly BSD .iso, and install it into an 18 gigabyte
"disk" (really a large file created with dd and reblock), and it's
just working beautifully. It didn't require a special version of the
OS (like Xen would), and I haven't seen any glitches yet.
Unfortunately, microsoft has purchased connectix. This may
have a negative impact on some of the commercial products' ability to stay
