Xen reboots

Asaf Maruf Ali

I am trying to run Xen on a Redhat like enterprise linux distro known as XOS.

Xen boots, sets up the memory and after some output reboots. I am unable to
boot.

I have attached the grub.conf file as well as the output of /boot partition.
Any help would be appreciated.


# grub.conf generated by anaconda
#
# 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.
#          root (hd0,0)
#          kernel /vmlinuz-version ro root=/dev/hda2
#          initrd /initrd-version.img
#boot=/dev/hda
default=1
timeout=10

Re: Xen reboots

Czerwinski
You could try the "noreboot" kernel parameter an provide some additional  
error messages.
