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

[Jignesh Patel <j4sangoma@xxxxxxxxx>]

Hello,

I need help get working my NIC with Xen domU. 

I can see the NIC card from domU but cannot get it to work. The same network card will work fine on the dom0.

When I unplug and plug the network cable from the NIC, I can see in the system log:

[  151.770678] eth0: link down

 eth0: link up, 100Mbps, full-duplex, lpa 0x45E1

But when I do "/etc/init.d/networking restart", I cannot see DHCP request coming to my router.

The same NIC will work fine on dom0. 

Can some one check my configuration ?

I know that PCI hide works as I can see

# xm pci-list-assignable-devices
