[Xen-users] Can't get PCI device access in domU to work

[als@xxxxxxxxxxxxxxx]

Hi,

I'm running Xen 2.0.7 with Linux as domain0 (Linux 2.6.11.12-xen0),
built from source.

Running Linux 2.6 guest donmains with the default xenU kernel works
fine. But I can't run Linux 2.6 guest with access to PCI devices.

I successfully hid the PCI devices (network cards) from domain0 using
the physdev_dom0_hide parameter (lspci in domain0 doesn't find the
anymore). Next I rebuilt the linux-2.6.11-xenU with physical device
access  and PCI support (but no drivers yet, I just wanted to see wether
the guest domain can find the PCI device) added to the configuration
options. I also added  pci = [ '02,0d,0' ] to the domain config file.

Upon trying to create the guest domain with the new kernel it
immediately crashed without any console output from the guest kernel.

What am I doing wrong?

The relevant part from the xend.log:
