It is true that it is too slow for "real" work that is
cpu-bound, if the kqemu acelerator module is not used.
But if you just want to test if an ISO image is bootable,
then qemu is fast enough.  In fact, booting a FreeBSD CD
up till the Login prompt is faster in qemu than on real
hardware.

So far, qemu has worked perfectly fine (and fast!) for
me for all purposes, so I haven't had a need for Xen.
However, I'm using qemu on FreeBSD with the kqemu module.
As far as I know, that module doesn't work on DragonFly,
unfortunately.  Well, at least DragonFly can run _inside_
qemu without problems.  :-)
