Re: [xcat-user] Adding extra kernel modules

Thanks! I have tried that, but have not been able to get it to work as intended.

Where does xCAT look for the "replacement" drivers? If you specify, for example, "genimage -n foobar", where would one then place the foobar driver for xCAT to pick it up and place it in the image for you?

For the kernel drivers, just use the genimage -n nodenetdrivers is enough.

But one think you need to know that if you specifying the -n, it means replacing the default driver list instead of appending. That means you'd better add the default ones in the -n with your specific drivers.

The default drivers for rh x86_64 is: tg3 bnx2 bnx2x e1000 e1000e igb mlx_en virtio_net be2net

 
Thanks

Thanks!

I was speaking more towards adding drivers to a stateless image, for example an updated tg3 nic driver.

You can of course just unpack the initrd, manually add the .ko file in, and repack it, however I was wondering if there is a better supported way to have xcat automate this piece.

    Hi all,

    What is the proper "xcat-supported" way of adding extra kernel modules
    into a stateless Linux image? I have found some fairly old docs stating
    to copy them to /opt/xcat/share/xcat/netboot/$OS, list them in the
    genimage "-n" option, and xcat will pick it up and copy it into the
    image/initrd for you, but I have been unsuccessful in getting that to
    work with my 2.6 setup.
