I haven't tried XEN yet (probably won't in the near future, as I just
started a bachelor's program), but have tried QEMU. Two suggestions if
you do try it:

1) Don't try to use a package, download from the site and compile by
hand.
2) Don't use just QEMU, use the accelerator module as well (kernel
module). QEMU without the accelerator is *slow* in my experience, and
(when emulating x86 on x86) quite snappy with.

Here's the URLs:

HTH a bit,
