R: [Xen-users] BROADCOM 5708 ON POWER EDGE 1955

["Carlo Granisso" <carlo@xxxxxxxxxxx>]

I can't. My system must boot via pxe (with xen 3.1 kernel).
Is there other way?

Hi

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:


Xen:

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
