thanks for that.

I actually wanted to use the source code as I wanted to make small
changes to XEN and recompile it. If I use the RPM can I recompile the
code?
Oh, yes. Start with the SRPM, and be ready to spend some time waiting for it to compile. And make sure to reset the %release setting in the .spec file.


I tried making changes to the grub.conf file. It has the following
contents, my paths are relative to /boot:

title Fedora Core (2.6.18-1.2798.fc6)
        root (hd0,0)
        kernel /vmlinuz-2.6.18-1.2798.fc6 ro
root=/dev/VolGroup00/LogVol00 rhgb quiet
        initrd /initrd-2.6.18-1.2798.fc6.img
title XEN 3.1 /XenLinux 2.6
        kernel /xen-3.1.gz console=vga
        module /vmlinuz-2.6-xen root=/dev/VolGroup00/LogVol00 console=tty0

I made these entries using the documentation on XEN.  On booting that
kernel it displays some commands and then it displays kernel panic and
reboots the machine.

Is it because I dont have an initrd entry for it? There is no initrd
file corresponding to XEN in the boot directory.

thanks & regards.
You do have a /boot partition of its own, as partition 0 on hard drive 0 (which you can look up in /boot/grub/device.map), right? And why not boot with your installation CD in "rescue" mode in order to get at and play with the grub configuration as needed?

Also, I would *not* put a "/" in a title.

And last, how did you install your Xen kernel? See, the SRPM does all that for you, but did you do a "make install" with it? That should have given you an initrd.
