Config file

kernel = "/boot/vmlinuz-2.6.18-xen"
ramdisk = "/boot/initrd-2.6.18-xen.img"
name = "ldap"
memory = "1024"
disk = [ 'phy:/dev/VolGroup00/ldap,sda1,w']
root = "/dev/sda1 ro"
vif = [ 'mac=00:16:3e:12:34:a8, bridge=xenbr0', ]
uuid = "bee5f62b-7193-a454-e37e-a151a5be8f45"
vcpus=7

The above domU was booting up properly so i am guessing its an issue with
the way i have setup xen.
