  • Thread-topic: Missing initial RAM disk after Xen installation

After installing the Xen RPMs on SUSE Enterprise Linux Desktop, I edited /boot/grub/menu.lst file to include:

title SUSE with Xen (2.6.18-xen_3.1.0)
root (hd0,0)
kernel /boot/xen-3.1.0.gz
module /boot/vmlinuz-2.6.18-xen_3.1.0 ro root=/dev/hda2
module /boot/initrd-2.6.18-xen_3.1.0.img

(based on the advice in the readme file at http://www.xensource.com/download/docs/README-xen31-hostrpms.txt)

Unfortunately this fails at the initrd stage with GRUB error 15 (file not found). Digging further, I can see that although a symlink has been created from initrd-2.6-xen.img to initrd-2.6.18-xen_3.1.0.img, initrd-2.6.18-xen_3.1.0.img does not seem to exist.

I think I've found out why the image is missing, but I'm still stuck! After removing Xen and the Xen kernel, then reinstalling in a terminal (rather than by double-clicking the RPM file), I saw this:

hostname:/home/mark/Desktop # rpm -ivh xen-3.1.0-1.i686.rpm
Preparing... ########################################### [100%]
1:xen ########################################### [100%]
hostname:/home/mark/Desktop # rpm -ivh kernel-xen-2.6.18-3.1.0.i686.rpm
Preparing... ########################################### [100%]
1:kernel-xen ########################################### [100%]
/sbin/mkinitrd: line 2958: /boot/initrd-2.6.18-xen_3.1.0.img/etc/fstab: No such file or directory
No '/' mountpoint specified in /boot/initrd-2.6.18-xen_3.1.0.img/etc/fstab

It seems that there is a problem with the RPM... Please can anyone help me work around this?

Cheers, Mark
