you upgraded the host kernel? in this case, is the new one xen-enabled? because the domain0 kernel should always be modified for xen...

if it is xen-modified, is xend running? open a console, type

xm list

to see if the dom0 is listed....if your new kernel is not xen-modified, (plus maybe xen isnt loading at all), you should still have an option to boot into the old kernel thru grub when you start the computer...

Hi all,

I've a little problem here.
I'm using SuSE 10.1 as a host system. I had various virtual machines
(debian,centos,SuSE,...) running on it.
Last week I did a full upgrade on the host system, even a new kernel.
After the upgrade all virtual systems had problems, which lasted in
not be able to boot systems.

I know what happened, but my question: Is there a way to upgrade a
host system without needing to touch the virtual machines? Or do I
always have to patch a virtual host after patching the host system
Would this be possible with the virtual system supporting hardware
from Intel/AMD?
