Install nova using the following commands:

sudo apt-get install nova-api nova-cert nova-compute nova-compute-kvm nova-doc nova-network nova-objectstore nova-scheduler nova-volume rabbitmq-server novnc nova-consoleauth

Create a Physical Volume.

sudo pvcreate /dev/sda6

Create a Volume Group named nova-volumes.

sudo vgcreate nova-volumes /dev/sda6

Change the ownership of the /etc/nova folder and permissions for /etc/nova/nova.conf:

sudo chown -R nova:nova /etc/nova
sudo chmod 644 /etc/nova/nova.conf

Open /etc/nova/api-paste.ini and at the end of the file, edit the following lines:

admin_tenant_name = %SERVICE_TENANT_NAME%
admin_user = %SERVICE_USER%
admin_password = %SERVICE_PASSWORD%

These values have to be modified conforming to configurations made earlier. The admin_tenant_name will be 'service', admin_user will be 'nova' and admin_password is 'nova'.

After editing, the lines should be as follows:

admin_tenant_name = service
admin_user = nova
admin_password = nova

Create nova schema in the MySQL database.

sudo nova-manage db sync

Provide a range of IPs to be associated to the instances.

sudo nova-manage network create private --fixed_range_v4=192.168.4.32/27 --num_networks=1 --bridge=br100 --bridge_interface=eth1 --network_size=32 

Export the following environment variables.

export OS_TENANT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=admin
export OS_AUTH_URL="http://localhost:5000/v2.0/"

Restart nova services.

sudo restart libvirt-bin; sudo restart nova-network; sudo restart nova-compute; sudo restart nova-api; sudo restart nova-objectstore; sudo restart nova-scheduler; sudo restart nova-volume; sudo restart nova-consoleauth;

To test if nova is setup correctly run the following command.

sudo nova-manage service list
Binary           Host              Zone             Status     State Updated_At
nova-network     server1           nova             enabled    :-)   2012-04-20 08:58:43
nova-scheduler   server1           nova             enabled    :-)   2012-04-20 08:58:44
nova-volume      server1           nova             enabled    :-)   2012-04-20 08:58:44
nova-compute     server1           nova             enabled    :-)   2012-04-20 08:58:45
nova-cert        server1           nova             enabled    :-)   2012-04-20 08:58:43

If the output is similar to the above with all components happy, your setup is ready to be used.
