Booting Kernel inside the Xen Paravirt Dom U

記錄一下
先create image，然後將Dom 0的

#xen-create-image --hostname=squeeze-1 --size=8Gb --dist=squeeze --memory=256M --dhcp
....
#mount -o loop=/dev/loop2 /home/xen/domains/squeeze-1/disk.img /mnt/
#cd /mnt/boot
#cp /boot/vmlinuz-2.6.26-1-xen-686 ./
#cp /boot/initrd.img-2.6.26-1-xen-686 ./
#mkdir grub
#cd grub/
#cp /boot/grub/* ./
#vim device.map
#vim menu.lst
# cat device.map
(hd0) /dev/sda
## cat menu.lst
...
...

title Debian GNU/Linux, kernel 2.6.26-1-xen-686
root (hd0)
kernel /boot/vmlinuz-2.6.26-1-xen-686 root=/dev/sda ro quiet
initrd /boot/initrd.img-2.6.26-1-xen-686

title Debian GNU/Linux, kernel 2.6.26-1-xen-686 (single-user mode)
root (hd0)
kernel /boot/vmlinuz-2.6.26-1-xen-686 root=/dev/sda ro single
initrd /boot/initrd.img-2.6.26-1-xen-686

最後就是/etc/xen/squeeze-1.cft中的設定，要指定kernel位置以及root fs的位置

#
# Configuration file for the Xen instance squeeze-1, created
# by xen-tools 3.9 on Thu Jan 5 17:35:59 2012.
#

#
# Kernel + memory size
#
kernel = '/boot/vmlinuz-2.6.26-1-xen-686'
ramdisk = '/boot/initrd.img-2.6.26-1-xen-686'
memory = '256'

#
# Disk device(s).
#
root = '/dev/sda ro'
disk = [
'file:/home/xen/domains/squeeze-1/swap.img,sda1,w',
'file:/home/xen/domains/squeeze-1/disk.img,sda,w',
]

指定disk.img export 到/dev/sda，然後再指定root是/dev/sda
