Hello again,

I'm still having problems to automatically give a pci device to a DomU.

I put the "pciback.hide=(00:1d.0)(04:00.0)" argument to grub.

While passing the device id to the "xm" command works it do not in the configuration file with the line : pci = ['00:1d.1','04:00.0']

Here is the result of the command :

xen:~# xm create vm.fp
Using config file "/etc/xen/vm.fp".
Error: pci: PCI Backend does not own device 0000:00:1d.1
See the pciback.hide kernel command-line parameter or
bind your slot/device to the PCI backend using sysfs

I tried with "echo -n ..." but i got an error message too :

xen:~# echo -n 0000:00:1d.1 > /sys/bus/pci/drivers/pciback/new_slot
xen:~# echo -n 0000:00:1d.1 > /sys/bus/pci/drivers/pciback/bind
-bash: echo: write error: Aucun peripherique de ce type

Which means "no type of this device".

Any help would be great.

Hi all,

This has, i'm sure, been told a lot of time but i haven't found any things to solve my problems.
Here is it:

I wan't to export a usb port on DomU (CentOS 5) from my Dom0 (Debian Etch).

I have only succeded with the pci export but with the next command: "xm create machine pci=00:1d.0"

With having many differents syntaxes in the machine configuration file would not work for me.

Does anybody know how to do it in the conf file?

Or perhaps with a usb export (it would be what i want finally)?

Xen version : 3.0.3-1 from Debian stable packages
