[Xen-users] trouble with dedicated network card and pciback

[Daniel Davidson <danield@xxxxxxxxxxxx>]

Hello,

I have been trying to get a dedicated network card working with pciback
and xen over the past few days with no success, I am wondering if anyone
could clue me in to what I am missing.  I am using RHEL 5.3 with a Intel
Pro 1000 network card that needs to be used for the vm.

>From Dom0 I get the following:

[root@cl-file ~]# lspci |grep -i ethernet
03:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5708
Gigabit Ethernet (rev 12)
07:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5708
Gigabit Ethernet (rev 12)
0d:00.0 Ethernet controller: Intel Corporation 82572EI Gigabit Ethernet
Controller (Copper) (rev 06)

The Intel card is what I need to use, so my pci id should be 0d:00.0

Pciback has the device:

[root@cl-file xen]# dmesg |grep pciback
pciback 0000:0d:00.0: seizing device

I then add pci=['0000:0d:00.0'] to my file for the vm, all lines of
which follow:

name = "windows-citrix"
uuid = "4be7bc1b-4266-a3d8-59ac-01fa9cf89e34"
maxmem = 3999
memory = 3999
vcpus = 1
builder = "hvm"
kernel = "/usr/lib/xen/boot/hvmloader"
boot = "c"
pae = 1
acpi = 1
apic = 1
localtime = 1
on_poweroff = "destroy"
on_reboot = "restart"
on_crash = "restart"
device_model = "/usr/lib64/xen/bin/qemu-dm"
usbdevice = "tablet"
sdl = 0
vnc = 1
vncunused = 0
keymap = "en-us"
vncdisplay = "2"
disk = [ "file:/external/windows-citrix.img,hda,w",
"file:/root/drivers.iso,hdb:cdrom,r" ]
pci=['0000:0d:00.0']
#vif = [ "mac=00:16:3e:0b:5d:d9,bridge=virbr0" ]
serial = "pty"

I also edited the pci-permissive file to add the device there:

[root@cl-file xen]# lspci -n |grep 0d:00.0
0d:00.0 0200: 8086:107d (rev 06)

The file contains:

(unconstrained_dev_ids
     #('0123:4567:89AB:CDEF')
        ('8086:107d')
)

However now when I try to install the Intel drivers on my windows 2008
server 64 bit vm, it fails to find the card.  Any ideas?

Dan
