At the initial stages of booting, the ''/boot'' filesystem
isn''t mounted at ''/boot'', but rather at
''/''. Try changing the menu.lst from
''/boot/xxx'' to just ''/xxx'' and see if that
works.
Thanks,
Phil.

The root statement in grub.conf has not necessarily anything to do with the root (/) partition of your system.

That is the one you feed to grub.conf to find your boot files. From your grub.conf file (with small change): title Red Hat Enterprise Linux AS-up (2.6.9-67.EL) root (hd0,0) kernel /vmlinuz-2.6.9-67.EL ro root=/dev/VolGroup00/LogVol00 > rhgb quiet initrd /initrd-2.6.9-67.EL.img title Xen 3.0 / XenLinux 2.6 root (hd0,0) kernel /boot/vmlinuz-2.6.18-xen root=/dev/VolGroup00/LogVol00 ro > rhgb Apparently, something is missing from this file. Here is an example from my grub.conf file: # Xen 3.2 experiment title CentOS (2.6.18-53.1.14.el5xen) XEN 3.2 FROM XENSOURCE root (hd0,0) kernel /xen.gz-3.2 com2=19200,8n1 console=com2,vga module /vmlinuz-2.6.18-53.1.14.el5xen ro root=LABEL=/1 > console=xvc xencons=xvc module /initrd-2.6.18-53.1.14.el5xen.img First, the /boot disk (/dev/sda1) is given as "root" for this grub config file. So all files in that partition are now in "/" (as Phillip already pointed out). Second, you need to define the kernel to load, which is Xen. The console is attached to /dev/ttyS1 on my server as it contains an IPMI card for remote console. You won''t need those com2= console= parameters. Third, you need to define the Linux kernel and initrd images as modules. In your case, without the console= and xencons= parameters.

Hi;
İ have done all the stuff that you explain (thanks for all of course) and try to
boot xen but now i have another problem that "kernel panic : unable to
mount root fs on device (0,0)"
Is there something about volume manager?
My final grub is

# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.

# initrd /initrd-version.img
#boot=/dev/sda

You forgot the initrd module statement in grub.conf. So the kernel misses the device mapper module ("driver") that is in the initrd. Just add "module initrd /initrd-<version>.img" to grub.conf. You might need to create it with the mkinitrd command if it is not in /boot already. BTW. Why are you using Xen 3.1?
