Current cvs / the next qemu version will allow more to be virtualized
(and therefore require less emulation), and people are reporting speeds
in the same ballpark as vmware -- though I haven't tried the additional
virtualization myself yet. See  and the rest of the thread.

VMware is most certainly a very good and polished product and faster
than qemu at the moment, I agree with you 100% there. Mentioning qemu
was just an idea for people who didn't want to spend any money :)
Also qemu has some interesting extra features, though these will
probably be of lesser interest to people who only wish to run windows.

Qemu itself is LGPL, the kernel module is proprietary (but gratis).
There is a GPL'd kernel module (qvm86) that does the same job and
hopefully this situation will improve in the future (i.e. both
maintainers working on a GPL'd kernel module).
