Rackspace has released a new version of its private cloud offerings. The new private cloud is based on the lasted Folsom Openstack release and includes many of the latest features.

ISO downloading 

The software can be downloaded fro after you fill in a simple form. Once filled you receive an email with a direct link to download the ISO image (alamo-v2.0.0.iso). The other important link is Getting Started Guide document.

To start the installer I had to first convert the ISO into a bootable USB (In the guide you find a link to this tool that can help you with this task

Once done change the boot sequence in BIOS, plug your Pendrive and restart the server.

The installation is relatively simple. The couple of questions that you may get confused are about the number of NIC and what subnet do you want to use for the cloud servers.

Below are some of my screenshots to demonstrate how it looks like (sorry for the quality)

The installation welcome screen

There will be couple of questions for IP address, gateway, netmask, DNS, user, password that you have to answer as well. Random screenshots are showed below.

During the whole installation you can switch to console 4 (ALT+4) and observe various debugging logs as the installation progresses.

At some point the phase 1 of 2 will be completed and the system reboots. Once the system come back we can see different logs showing how the chef progress as Openstack is configured.

At the end of phase 2/2 when the installation is completed you are going to see a screen with summaries about the server resources.
