[Xen-users] Xen interoperability among different version

[Thomas Maschutznig <thomas.maschutznig@xxxxxxxxxxxxxx>]

Hi Xen list!

My question might be pretty dumb but please bear with me :-)
In which way are the different versions of Xen and versions of (Linux) 
kernels patched with Xen interoperable among each other?
I tried Xen on a Fedora Core 4 system (kernel 2.6.11-1.1369_FC4xen0) and 
whenever I would start a domU using the official 2.0.6 
vmlinuz-2.6.11.10-xenU or vmlinuz-2.4.30-xenU kernel, I'd get:
Using config file "foo.conf".
Error: Error creating domain: (0, 'Error')

Here are the according entries in xm log:
[2005-06-27 03:41:13 xend] DEBUG (XendDomainInfo:770) init_domain> 
Created domain=1 name=ttylinux memory=6144

Traceback (most recent call last):

line 107, in _perform
    val = op_method(op, req)
  File 
"/usr/lib/python2.4/site-packages/xen/xend/server/SrvDomainDir.py", line 
71, in op_create
    raise XendError("Error creating domain: " + str(ex))
XendError: Error creating domain: (0, 'Error')
[2005-06-27 03:41:14 xend] INFO (XendRoot:112) EVENT> 
xend.console.create [13, 1, 9601]
I tried another domU conf and got the same result with the two kernels 
from Xen Downloadpage.
Did I miss anything?

cheers,
 thomas
