Re: [Xen-users] Xen-4.0.1 PCI cannot get nework card to work

[Jignesh Patel <j4sangoma@xxxxxxxxx>]

Hi Todd,
1) lspci -vvv on the domU guest
==>

2) the tail of the dmesg just after running the dhcp client (dhclient on debian)

 I don't have dhcp client running on debian (dom0). The IP is provided by the gateway router.
 On Gateway Router log I don't see DHCP request from domU when I use the Realtek card with pci passthrough.

From xenstore-ls :

 pci = ""
     2 = ""
      0 = ""
       domain = "sangomatest"
       key-0 = "08:01.0"
       vdevfn-0 = "100"
       uuid = "00ca7504-f956-8a08-4e0d-b67a526a16f3"
       dev-0 = "0000:08:01.0"
       frontend = "/local/domain/2/device/pci/0"
       state = "4"
       >
       frontend-id = "2"
       uuid-0 = "089bc4f9-9e74-f7d7-32a4-54d164c1d9af"
       num_devs = "1"
       vdev-0 = "0000:00:00.00"
       state-0 = "3"
       root-0 = "0000:00"
       root_num = "1"



Could this be configuration issue ? 


Thank you,

Jignesh

Could you also provide the following?

1) lspci -vvv on the domU guest

2) the tail of the dmesg just after running the dhcp client (dhclient on debian)

You may also want to do some reading on threads related to xenstore-ls and pci

See for example: http://xen.markmail.org/search/?q=xenstore-ls+pci

You may be able to provide more information on specifically what is
being created for the device in xenstore. I don't know the specifics,
but those threads might help or give debugging tips.

Hope that helps.

Thanks,
Todd
