hi all,

i want to install xen3.1 on my system, suse linux
enterprise server 10 SP1 (kernel 2.6.16.46-0.12).
i download the tarball binary file. it contains only
"vmlinuz-2.6.18-xen" and "xen-3.1.gz ", no initrd. but
see the following code in my grub menu.lst, it seems
like i need the initrd file.

i tried the installation with this binary Tarball, it
didn't work.

this is the original code in menu.lst of GRUB:
--------------------------------------------------
title SUSE Linux Enterprise Server 10 SP1
   root (hd0,1)
   kernel /boot/vmlinuz-2.6.16.46-0.12-default
root=/dev/sda2 vga=0x32b    resume=/dev/sda1
splash=silent showopts
   initrd /boot/initrd-2.6.16.46-0.12-default
--------------------------------------------------

i don't know what the problem is. So i want to install
from source, and i want to build a xen linux kernel
with the same kernel version of my suse
(2.6.16.46-0.12). I looked up the xen manual, but it
shows not enough details of the installation steps.

Could you please tell me which steps shall i do in the
installation?

You should be able to create the initrd with a mkintrd or mkintramfs command.

The basic idea is to pass those commands the proper kernel version. The kernel and the modules (that make up the initrd) need to make. So in your case I would expect that you should be able to find the proper modules in  /lib/modules/2.6.18-xen. You then also need to pass the output file name as the initrd file. (Note, typically the command takes on the 2.6.18-xen part and not the /lib/modules part, as that is assumed.

You should be able to find good examples of using the proper mkinitrd or mkinitramfs command online and I believe they also explain that in the README that comes with the binary package.

Todd

 

thanks a lot.

best regards,
