    $ cd contego
    $ sudo python setup.py develop
    
    # mount the nfs export where the backups will be stored
    $ sudo mkdir /var/triliovault
    $ sudo chmod +rw /var/triliovault
    $ sudo mount server:/export /var/triliovault

    
    # Modify your etc/nova/nova.conf to include the API extension in the DEFAULT section
    # if using devstak you need to do this everytime your run the devstack
    osapi_compute_extension=nova.api.openstack.compute.contrib.standard_extensions
    osapi_compute_extension=contego.nova.osapi.contego_extension.contego_extension
    
    # Modify your etc/nova/rootwrap.d/compute.filters
    # if using devstak you need to do this everytime your run the devstack
