Hi guys.

I followed chapter 21.2.2 FreeBSD with Xen™ on Linux from:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/virtualization-guest.html
and installed linux-2.6-xenU kernel.
Unfortunatelly I get following error message trying to boot it on
NetBSD 4.0_RC1 from 3 September and XEN 3.1.0

# xm create debian
Using config file "/usr/local/etc/xen/debian".
Error: (2, 'Invalid kernel', 'xc_dom_compat_check: guest type
xen-3.0-x86_32p not supported by xen kernel, sorry\n')

Any idea what is wrong?
BTW, is there any repository of xen domU kernels and images like they
have for vmware?


Some more info:

# objdump -j __xen_guest -s vmlinux-2.6-xenU
