Re: [Xen-users] Xen reboots
by the way, I did this install with the precompiled xen, earlyer i tryed from
source xen 3.0.1 without sucess either.
Zitat von Seneca <acenes@xxxxxxx>:
I cant see anything wrong in the setup, and since it boots without
problems with your ubuntu 2.6.12 kernel it *should* also work with
the xen 2.6.16. There have been discussions about similar problems
and possible solutions in the thread below:
http://ubuntuforums.org/showthread.php?t=25938
Btw. did you install the precompiled xen 3.0.2 distribution or did you
compile it from source?

Hello Tulasi,
I see a misspeling in my suggestion, once it is
initrd.img-2.6.16-xen
and once
initrd.img-2.6.16.xen
It must be exactly the same of cause, otherwise the file will not be
found by grub.

Now this looks really odd. Could you post your /etc/fstab file,
the current menu.lst and a dir of /boot ?
