Re: FreeBSD as VM host OS?

Hello,

Not sure if this is what you are looking for, but you could also try BOCHS. It's a little slower, but runs on many platforms.

Cheers,
Lonnie

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

guests. i.e., you can't run Linux in a FreeBSD jail

HTH



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.
