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

[Ivan Porro <pivan@xxxxxxxxxxxxx>]

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
