hi,
thanks for your answer.

I' ve tested also xen-testing by mercurial this day.
I will try it with xen-unstable in the next days, when there is time for it.
But i think it could also be a bios related problem. 
I had same results with the q35 after biosupdate, restoring it to the first 
bios cleared the situation.

The motivation to write these mails was to find someone who can answer me if 
there are possibilities at the moment to use this feature or if i have to 
wait to a working bios or a newer xen-release.

I think my problem is the bios or xen.

Mfg Axel
