Tobias,

When I restart my domU, my domU freezes (the boot screen of Windows XP is frozen with blue progression bar). Only my dom0 is available.

David.

Hello,

glad to hear it works for you!

As i run a similar setup, perhaps you can share your experience regarding
DomU-Reboot with a VGA Card passed through to it: Does a reboot work, i.e.
does the passed-through VGA Card work after a DomU reboot?

My hole System (DomU + Dom0) freezes after a reboot of DomU (exaclty then,
when the passed-through VGA Card is accessed...), therefore the question.

Thanks for your info!
Greetings
Tobias
