[Xen-community] pcifront problem in Ubuntu 10.04 domU

[Francisco Barrera <francisco.barrera@xxxxxxxxx>]

Hi all,

I have a problem when from domU I need to configure a network interface.


My system configuration is the next:

dom0: xen 3.4.3 with 2.6.18-238.9.1.el5xen kernel, making pci back from a network card. All ok. This is the result from "lspci -v -s 09:00.0"
09:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet (rev 12)
Subsystem: Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet
Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 255
Memory at d2000000 (64-bit, non-prefetchable) [size=32M]
Capabilities: [40] PCI-X non-bridge device
Capabilities: [48] Power Management version 2
Capabilities: [50] Vital Product Data
Capabilities: [58] MSI: Enable+ Count=1/1 Maskable- 64bit+
Kernel driver in use: pciback
Kernel modules: bnx2

domU: paravirtual Ubuntu 10.04  with 2.6.37-020637-generic kernel

Apparently works fine, because I execute from dom0 when domU is created "xm pci-list Ubuntu" and the result is:
domain   bus   slot   func
0x0000  0x09   0x00    0x0

and from domU I execute lspci, it returns:
00:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet (rev 12)

This is a domU dmesg output:

But when I configure the network interface in /etc/network/interfaces file, and I execute "ifup eth1" the system hangs.
After rebooting, the message that appears is the next and the system dead:
