I've solved it.

You have to compile Xen kernel 3.1 from source. Then, you have to download drivers from Broadcom and compile your own kernel module for network.

hope it helps


From my twiki:


wget http://bits.xensource.com/oss-xen/release/3.1.0/src.tgz/xen-3.1.0-src.tgz
tar xzvf xen-3.1.0-src.tgz
cd xen-3.1.0-src
make -j4 world
make install

The DELL Power Edge 1950 like many other servers mount a Broadcom NetXtreme II controller, which may be slow, unstable or make network failing at all with Linux kernel before 2.1.19. Unfortunately, Xen 3.1 is configured to use 2.6.18 so we have to provide a new kernel. This should b done anyway since the 1.5.0c version of the driver is recommended.
This apply of course also to other kind of drivers.

Identify your hardware:

lspci |grep Eth

We have:

04:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet (rev 12) 08:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet (rev 12)

Donwload and compile drivers. If the link does not work, check on Broadcom web site, driver download section. Since we probably are with the machine booted on non-Xen kernel, we have to tell Makefile to use the right kernel when compiling:

mkdir /usr/src/driver
cd /usr/src/driver
wget http://www.broadcom.com/docs/driver_download/NXII/linux-1.5.10c.zip
unzip linux-1.5.10c.zip
mv Server/Linux/Driver/* .
tar xzvf bnx2-1.5.10c.tar.gz
cd bnx2-1.5.10c/
cd src/
make KVER=2.6.18-xen
make install KVER=2.6.18-xen

Since we have added a new module, we have to regenerate the ramdisk:

mkinitramfs -o /boot/initrd.img-2.6.18-xen 2.6.18-xen

Hello, I've this strange problem.
When Xen kernel start and it try to start eth devices, network doesn't work.

It seems to be a problem with NICs firmware.

Anyone had this problem? Do you know where I can download firmware upgrade?
(on DELL's site I've just searched...)
