Debian distributes Xen enabled freebsd kernel images in official repository. This is part of kfreebsd-* arch, but kernel images are also available for i386 and amd64 distributions (on Linux kernel), for easy installation. For example just do: apt-get install kfreebsd-image-9.0-1-xen and kernel should be available in the /boot/ directory. You can use this kernel to install both kfreebsd-* as well official freebsd using iso images. It doesn't involve compiling anything at all. I can find old post where I described it in detail. (it basically uses serial console to install freebsd using standard installer and standard iso image). Regards, Witek -- Witold Baryluk
