Re: [Xen-users] Error: pci: 0000:02:06.0 must be co-assigned to the same guest with 0000:02:05.0

Hi Velten,

you could try to put the isdn card in a different pci-slot.

You get around the "co-assigned" message with assigning the pci  
devices xen wants into one domU, however this might not be always  
possible ( eg. motherboard devices)
However, i am testing xen3.3.1 on opensuse11 at the moment and it looks
like the pv pci-passtrough is seriously broken.

pv pci-passtrough worked wonderful in opensuse10.3 which xen 3.1.  
Trying the same ( with same domU config file) in xen3.3.1 just gives  
you the "co-assigned" and even worse, if you assign all pci devices  
xen wants in the domu, the domU starts, but it looks like the  domU  
does not get the interrupt from the device.
I believe the VT-d passtrough code messed up the pv passtrough, hope  
this gets fixed soon.
Regards

Frank
