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. - -Garrett -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFFhtuWEnKyINQw/HARAiU+AJ90UsopFNrxLn4/tEPObrgC8X/FRACfaJO1 D7jmswA5nlJ+zks2WTLJMR0= =U6GQ -----END PGP SIGNATURE-----
