Your success with kqemu probably depends on what architecture you are

I use qemu here. I run a windows XP pro VM and a FEDORA CORE 5 VM, inside a

My question is whether FreeBSD is a suitable _host_ OS for any virtual

Try qemu. Some people on this list (or maybe other FreeBSD lists--can't
remember :P), have reported success in using qemu as the host VM.
Xen is a royal pain, even though it is fast. I tried setting it up once
under Gentoo and it was trying to load a lot of services at boottime,
pulled in custom (Xen) kernel patched sources, etc. Needless to say, the
Xen patched kernel sources was the show stopper, because one never knows
what in the world the patches may do if installed with other patches.
Moreover, the Xen patches may wreak havoc with userland programs (like
Linux does on occasion), etc.
Just my .02.. qemu has a kernel module, but if you don't feel like
tainting the kernel with an alpha feature, their userland(-only) program
is fairly stable from what I have read.
The install for both OSes were slow but it's perfectly OK if you take into
account the disk emulation and all.
Besides that, no complains whatsoever !. Native speed ? on a VM ? only in jail
( I think) or dual boot, but qemu comes pretty close. I have them hooked on a
bridged network, with sound. and a big plus: no linux emulation required
(like vmware, which I tried to try but serial numbers and linux stuff made me
I hope this helps
