[Xen-users] BSD guest on Linux host

[Sebastian Smith <ssmith@xxxxxxxxxxx>]

Hi,

I am running a Xen 3.0.2 on a Debian GNU/Linux system.  The kernel version 
is 2.6.16.  In attempting to create BSD guests (both FreeBSD and NetBSD) I 
recieve the following error:
Error: (22, 'Invalid argument')

Here is relevant data from my xend.log:

****************************************************************************

The xend-debug log does not contain any information.

I'm not sure if this is relevant, but I notice that in the image sublist 
the type -- or what I assume is the type -- is 'linux'.
Here is the config file associated with the guest I'm trying to create:

fbsd7.cfg
****************************************************************************
# Kernel image file.
kernel = "/var/tmp/kernel-current"

# Initial memory allocation (in megabytes) for the new domain.
memory = 2048

# A name for your domain. All domains must have different names.
name = "FreeBSD"

disk = [ 'file:/var/tmp/mdroot-7.0,hda1,w' ]
****************************************************************************

The script always bombs out on line 188.  As you can see, I'm not 
specifically assigning any features.  Should I be?
All Linux guests are created without issue.

That's all I have ;)  Thanks in advance to anybody who can provide me with 
assistance.
