El Diablo – running Nova on Oneiric

On October 13, 2011 – the Oneiric Ocelot release will be available to Ubuntu Server users everywhere. With it, a new release of Nova, Swift and Glance called “Diablo” will be available for users to test drive for their EC2 compatible private cloud. Thierry Carrez, Openstack release manager and Ubuntu developer has a detailed blog post about the features of the last Nova milestone at his blog.

There has been a lot of changes between the Cactus release and Diablo release of Nova. This blog will help you get started running a basic cloud on Ubuntu Oneiric. So lets get started!

First install Nova and Glance, Glance is now required for the API server:
sudo apt-get install nova-api nova-compute-kvm nova-scheduler nova-network nova-objectstore nova-volume
rabbitmq-server dnsmasq glance bridge-utils euca2ools python-novaclient

You will need to setup a bridge, information on how to do it can be found at the Ubuntu Server Guide.

Once Nova and Glance is installed you have to setup Nova. Setting up Nova  is relatively easy to do, all you need to do is to type the following:

sudo nova-manage db sync
sudo nova-manage user admin [username]
sudo nova-manage project create [name of cloud] [username]
sudo nova-manage network create public 10.0.0.0/8 3 16 --bridge_interface=br0
sudo nova-manage project zipfile [name of cloud] [username]

Once the cloud is up and running you will need to have an image to run on your cloud. You can download the latest release from here.

To upload an image to your cloud is easy as well, all you have to do is the following once you download the image:

unzip nova.zip
source novarc
uec-publish-tarball [name of tarball] bucket [arch]
euca-add-keypair -k [name of key] > [filename]
chown 600 [filname]

Finally to run your instance all you have to do is:

euca-run-instance -k [name of key] [instance-id]

Once the image has started, you should have a virtual machine running on your workstation. So there you have it..an EC2 compatible cloud running on your workstation. If you find any bugs please report them in launchpad. The more users we get testing Nova on Ubuntu the better. If you have any question please let me know.
