Out of curiousity:

1) What kind of hardware are you trying to pass through?
2) Are you using VT-d?

I got this with a PCI express disk controller with VT-d, and I eventually gave up. I did manage to pass a PCI controller fine though. (The PCI only had one controller, where the PCI express had two on one card.)

Dear all,

I recently tried to upgrade my xen 3.2.1 installation (installed from sources) on
debian etch amd64.

Unfortunately xen 3.3.0 PCI device delegation does not work anymore.
I receive the following error: device ... must be co-assigned to the same guest.

I already had a look to this thread: [Xen-users] xen 3.3.0 PCI device must be co-assigned to the same guest
from [Andy Burns] but did not see any solution for me so far.

Any help on this issue would be highly appreciated.

Best regards, Dieter
