[Xen-users] New DomU on older Dom0

[Danilo Godec <danilo.godec@xxxxxxxxx>]

Hi,

I have a Xen server running OpenSuSE 10.2, with Xen version 3.0.3_11774.
It's happily hosting two DomU's running the same OS / kernel.

Now I tried to create a new DomU running a newer OS - OpenSuSE 11.1. It
comes with Xen version 3.3.1_18494_03.

Unfortunately for me, it doesn't work - this is what I get:
> xen1:/etc/xen/vm # xm create NEW
> Using config file "NEW".
> Error: (22, 'Invalid argument')
And this is what I get in /var/log/xen/xend.log:

Is there anything I can do to make it work - besides upgrading the Dom0
or running an older kernel on my new DomU?

 Thanks, Danilo
