Re: [Xen-users] "XENBUS: Device with no driver" errors on Debian

I understand these kernel versions use paravirt_ops or something. Does this mean there is no PCI passthrough support? Can these kernels even run with a 2.6.18 dom0? I have tried upgrading to 2.6.25-2 with no luck.

Can someone fill me in? I can't find any documentation about it anywhere. The debian package descriptions even fail to mention which kernels will and won't work as a dom0 - it's a matter of trial and error for new users it seems!

I have fixed the console by adding hvc0 to inittab, but still no luck with the PCI. Both errors still show in dmesg.

I am running debian lenny, with the standard Xen 3.2 packages, with the 2.6.18-6-xen-686 kernel as dom0, and 2.6.24-1-xen-686 as domU. Everything is working fine apart from the console and the PCI passthrough. I am getting these errors in the domU on startup:

XENBUS: Device with no driver: device/pci/0
XENBUS: Device with no driver: device/console/0

Does this mean the modules are missing? I have the linux- modules-2.6.24-1-xen-686 package installed in the domU, I can't understand what could be wrong. Do they need to built into the kernel or something?

pciback is working fine on the dom0:

pciback 0000:04:00.0: seizing device
pciback 0000:01:00.0: seizing device
pciback 0000:01:00.1: seizing device
pciback 0000:01:00.2: seizing device
pciback 0000:01:01.0: seizing device
pciback 0000:01:02.0: seizing device

Thanks
