hi to all. i'm trying to install freebsd as domU on linux xen-ified kernel and i followed steps suggested in this post http://lists.freebsd.org/pipermail/freebsd-xen/2008-October/000009.html. kernel customization works with no errors, so i presume i got a valid kernel for domU but when i try to start freebsd vm, this is the boot output: ================================================================================================= [root@bran xen]# xm create freebsd-63.py -c Using config file "./freebsd-63.py".
