I'm trying to get FreeBSD CURRENT working under Xen 3.4.1 using the Gentoo dom0 kernel 2.6.29.6 I downloaded and compiled the 8.0 svn version revision 197720 from http://svn.freebsd.org/base/head with the KERNCONF=XEN option but when I'm starting my domU I'm getting the following panic: WARNING: loader(8) metadata is missing!

I'm using the following boot line for pygrub: kernel /boot/kernel/kernel vfs.root.mountfrom=ufs:xbd0,kern.hz=100,kern.smp.disabled=1,boot_verbose=1,boot_single=1 I've tried it with and without the kern.smp.disabled option Does anyone have any ideas about what's going wrong?
