Step 2 : Convert ubuntu-9.04-server-amd64 HVM to PV
========================================================================

-> Login to HVM domU

-> Add apt source list for Debian Lenny. Create a file /etc/apt/sources.list.d/lenny.list with this content
########################################################################
deb http://ftp.debian.org/debian/ lenny main
deb http://ftp.debian.org/debian/ lenny-proposed-updates main
########################################################################

-> install Lenny's linux-image-xen-amd64
# for key in A70DAF536070D3A1 4D270D06F42584E6;do sudo gpg --keyserver subkeys.pgp.net --recv-key $key;sudo gpg -a --export $key|sudo apt-key add -;done
# sudo apt-get update
# sudo apt-get install linux-image-xen-amd64

-> edit /boot/grub/menu.lst. Add these lines on the end (adjust UUID with the one on your system and kernel version with the one you just installed)
########################################################################
title           Ubuntu 9.04, kernel 2.6.26-2-xen-amd64
uuid            8da532f7-9314-438b-8cc2-dc1da4ddb683
kernel          /boot/vmlinuz-2.6.26-2-xen-amd64 root=UUID=8da532f7-9314-438b-8cc2-dc1da4ddb683 ro
initrd          /boot/initrd.img-2.6.26-2-xen-amd64
########################################################################

-> also on /boot/grub/menu.lst, change the default entry to the one you just created (on my system, "default 3")

-> create a suitable upstart entry for hvc0
# cd /etc/event.d/
# sudo cp tty1 hvc0
# sudo sed -i "s/tty1/hvc0/g" hvc0

-> poweroff domU

-> Create domU PV config file. Here's mine
########################################################################
memory = "500"
maxmem = "8000"
cpus="1-7"
cpu_cap=100
cpu_weight=128
vcpus=8
vcpu_avail=1

vif = [ 'mac=00:16:3E:23:2C:52, bridge=br129' ]
disk =	[
	'phy:/dev/disk/by-path/ip-192.168.129.89:3260-iscsi-iqn.1986-03.com.sun:02:8f570606-7acc-cc9f-cfae-eda9a39a9208-lun-0,hda,w',
	]

vfb =['type=vnc,vnclisten=0.0.0.0']
bootloader="/usr/bin/pygrub"
########################################################################

-> start PV domU with "xm create -c" (don't forget the "-c". It's helpful for debug purposes)

-> almost done :) Now you should be able to acess PV domU either from xen text console or from VNC. Login to domU.

-> copy /boot/grub/menu.lst, put it somewhere safe. You might need it later if you decide to turn this domU back to HVM

-> update domU's grub
# sudo update-grub

-> change /boot/grub/menu.lst to have "default 0" again.

You're done :)
