[Xen-users] CONFIG_XEN_PHYSDEV_ACCESS in domainU

["Patrice" <patrice-xen@xxxxxxxxxx>]

Hi,

We have been using Xen for several months now and it works real great (we 
have it running on Intel SR1300, Intel SR2300 and PowerEdge 1850).
Now we need one unpriviledged host to be able to access directly 2 PCI cards 
(RocketPort and modem on PowerEdge 1850):
As soon as I set CONFIG_XEN_PHYSDEV_ACCESS=y for a domainU, I can no longer 
start the virtual host, there is nothing on the console but I get the 
following from the xend log:

How can I get more clues to what's going on ? Anybody able to get a similar 
configuration to work ?
Thanks for any help.

Patrice
