I've attached the openstack.pm that use the euca2ools APIs to communicate with

1. OpenStack Essex Installation 

I think one of the best installation instruction for OpenStack Essex on Ubuntu

2. Provisioning 'raw' file format image with IDE disk bus type (e.g., Windows 
XP images)

The OpenStack's default provisioning image type is 'qcow2' file format and 
'virtio' bus type, respectively. To test images with raw file format with IDE 
disk bus type, 
you need to configure /etc/nova/nova.conf and change 
/usr/share/pyshared/nova/virt/libvirt.xml.template as like below: 

(a) Add the following options to /etc/nova/nova.conf

(b) Change the following part in 
#set $root_disk_bus = 'virtio'  ==>  #set $root_disk_bus = 'virtio' => 'ide'

However, these are temporarily solutions for testing images with raw file 
format with ide bus type. It might cause problems when you provisioning of 
qcow2 file format with virtio disk bus type.
