   recently i am researching fast boot from linux kernel to Xen hypervisor, it means when linux is running on the real machine, i just want to switch to Xen hypervisor without going through bootloader. both linux and dom0 of Xen using the same filesystem. since we boot Xen with the following command in grub:

 title Xen 3.1.0 / XenLinux 2.6.18
      kernel /boot/xen-3.gz
      module /boot/vmlinuz-2.6.18-xen ro root=LABEL=/ rhgb quiet
      module /boot/initrd-2.6.18-xen.img 
it's different from linux, but i think there are something in common.
so is there any suggestions for me!
