Backport Intrepid Xen 3.3 Hypervisor to Ubuntu Hardy Dom0 (2.6.24-21-xen)

As of November 11 Intrepid Xen 3.3 Hypervisor may be back ported to Hardy Dom0 via repositories.
Following bellow is a brief instruction for installation from scratch Ubuntu Hardy Dom0 with 2.6.24-21-xen kernel
running with Xen 3.3 hypervisor. Install Ubuntu 8.04.1 Desktop and remove network manager :-
# apt-get remove network-manager
# gedit /etc/network/interfaces

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

# /etc/init.d/networking restart
# apt-get install ubuntu-xen-server

When done activate backports in /etc/apt/sources.list and load Synaptic Manager.
Mark for installation ;-

libxen3-dev
xen-doc-3.3
xen-hypervisor-3.3
xen-utils-3.3

and accept suggested conflict resolution.



Go through install and reboot with Xen 3.3 Hypervisor :-

Perform the test. Create Intrepid HVM DomU via profile :-
root@boris-desktop:/etc/xen/vm# cat *.hvm
kernel = “/usr/lib/xen/boot/hvmloader”
builder = ‘hvm’
memory = 2048
name = “IntrepidHVM”
vcpus = 1
vif = [ 'type=ioemu,bridge=eth1' ]
disk = [ 'phy:/dev/sdb5,hda,w!','phy:/dev/loop0,hdc:cdrom,r']
device_model = ‘/usr/lib/xen/bin/qemu-dm’
vnc=1
boot=’d’

To evaluate hypervisor load Interpid PV DomU utilizing same image device :-

root@boris-desktop:/etc/xen/vm# cat *.py
name = ‘IntrepidPV’
bootloader=”/usr/bin/pygrub”
memory = 2048
disk = ['phy:/dev/sdb5,hda,w']
vif = [ 'bridge=eth1' ]
vfb = ['type=vnc,vncunused=1']
on_reboot = ‘restart’
on_crash = ‘restart’

# xm create intrepid.py
# vncviewer localhost:0
