> What domU kernel are you using? Does it have xen-pcifront?
I first used not a own domU kernel (dom0 Kernel: 2.6.32-5-xen-amd64). This did not wirk, the netowrk came up and got down immediately:
[ 260.736409] e1000: eth1 NIC Link is Up 100 Mbps Full Duplex, Flow Control: RX/TX
DHCPDISCOVER on eth1 to 255.255.255.255 port 67 interval 5
[ 261.552116] e1000: eth1 NIC Link is Down
[ 264.768408] e1000: eth1 NIC Link is Up 100 Mbps Full
Duplex, Flow Control: RX/TX
[ 265.580116] e1000: eth1 NIC Link is Down
DHCPDISCOVER on eth1 to 255.255.255.255 port 67 interval 8
[ 267.200418] e1000: eth1 NIC Link is Up 100 Mbps Full Duplex, Flow Control: RX/TX
[ 268.012111] e1000: eth1 NIC Link is Down
[ 269.632409] e1000: eth1 NIC Link is Up 100 Mbps Full Duplex, Flow Control: RX/TX
[ 270.444115] e1000: eth1 NIC Link is Down
I then followd the instructions on http://wiki.debian.org/PyGrub and used the 2.6.18 kernel, but this did not change anything.> What does "lspci" show in the domU?
domU:~# lspci
00:00.0 Ethernet controller: Intel Corporation 82541PI Gigabit Ethernet Controller (rev 05)
> What pci related do you have in the domU dmesg?
