Hi,
I'm testing driver domain(PCI passthru) on Fedora Core 5 + xen-3.0.2-2.
And I got trouble in DomU configuration.
I compiled xen from source(xen-3.0.2-src.tgz) and installed it.
I changed grub.conf, add pciback.hide=(03:0b.0) .
This is a PCI Bus-number of my second NIC.
That NIC disappeared from ifconfig in Dom0.
Then, I start DomU like this, xm create pci=03:0b.0 -c guest1.conf .
However, NIC cannot see in the guest.
The lspci command said `pcilib: Cannot open /proc/bus/pci
lspci: Cannot find any working access method.' in domU.
Is something wrong?
I also tried adding "pci=['03:0b.0']" line in guest configuration.
It also failed.
In boot message of domU, XENBUS timeout message had been indicated.

Thanks in advance!
