[Xen-users] Network problem in domU

[Francisco Barrera <francisco.barrera@xxxxxxxxx>]

Hi all,

my problem is that I have made in an Ubuntu 10.04 domU, pciback for a Ethernet card, and when I try to ifup eth1, the system crash.

All seems ok, in fact, when I execute "lspci" in domU, I get the pci id device: 
00:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet (rev 12)

The network card driver is loaded fine. This is the result of dmesg | grep -E "bnx2|eth" on domU:

[   13.490065] eth0: no IPv6 routers present

When I execute "ifup eth1", the system hangs, and after force reboot, I get the next message:

The curious thing, is that the two IP address configured, are able to respond to ping requests, but not at the ssh request.

My dom0 xen version is 3.4.3 and 2.6.18-238.9.1.el5xen kernel on top of Centos 5.6
The domU is a paravirtual Ubuntu 10.04 with 2.6.37-020637-generic kernel.


Please, any help are wellcome.
Thanks in advance.
