Hi,
I am (re)posting this here as I haven't had much luck on the xen user
mailing list.
I am using FC5 and xen 3.0.2 (what comes with yum).
I am trying to assign a pci or usb port to a domU. I get to the point where
pciback seizes the devices (5 usb and 2 pci) by modifying the
/etc/modprobe.conf configuration as explained in
http://wiki.xensource.com/xenwiki/Assign_hardware_to_DomU_with_PCIBack_as_module.
I then modified the configuration of the domU with pci = [ '00:1d.0' ,
'00:1d.1' , '00:1d.2' , '00:1d.3' , '00:1d.7', '02:01.0' , '02:02.0' ] but
nothing shows up in the domU. I also tried adding the parameter in the
command line (xm create domu pci=...).
[root@web ~]# lsusb
[root@web ~]# lspci
pcilib: Cannot open /proc/bus/pci
lspci: Cannot find any working access method.
[root@web ~]#
How can I make the domU recognize the two LAN interfaces and 2 usb devices
(usb drive and ethernet interface) plugged in? Could it be that these
devices do not have drivers? How can I check/fix that?
Here is part of the dmesg
pciback 0000:00:1d.0: seizing device
pciback 0000:00:1d.1: seizing device

ACPI: PCI Interrupt 0000:00:1d.0[A] -> GSI 16 (level, low) -> IRQ 20
After I start the domU
pciback: vpci: 0000:00:1d.0: assign to virtual slot 0
pciback: vpci: 0000:00:1d.1: assign to virtual slot 0 func 1
pciback: vpci: 0000:00:1d.2: assign to virtual slot 0 func 2
pciback: vpci: 0000:00:1d.3: assign to virtual slot 0 func 3
pciback: vpci: 0000:00:1d.7: assign to virtual slot 0 func 7
pciback: vpci: 0000:02:01.0: assign to virtual slot 1
pciback: vpci: 0000:02:02.0: assign to virtual slot 2
There is an eror message in xm dmesg but, from what I read, it does not seem
to be a problem. (XEN) DOM4: (file=mm.c, line=578) Non-privileged attempt to
map I/O space 00000000 (XEN) DOM4: (file=mm.c, line=578) Non-privileged
attempt to map I/O space 00000000
This is what I get from lsusb when I do not assign it to a domU
