[Xen-users] freebsd under xen

[Folkert van Heusden <folkert@xxxxxxxxxxxxxx>]

Hi,

I'm trying to run FreeBSD as a guest on a Xen system.
Dom0 is running.
It is an Intel E6600 system with VT support (64bit also).

I get the following errors:

belle:/vms# cat /var/log/xen/xend-debug.log
ERROR: Not a Xen-ELF image: No ELF notes or '__xen_guest' section found.
ERROR: Error constructing guest OS

while it really is a valid elf image:

belle:/vms# file freebsd-XENU_INSTALL
freebsd-XENU_INSTALL: ELF 64-bit LSB executable, x86-64, version 1 (FreeBSD), 
dynamically linked (uses shared libs), not stripped

anyone got a suggestion?

the freebsd-XENU_INSTALL is the kernel from /boot/kernel/kernel from a FreeBSD 
boot-cd
