Chapter 8. Using Nova
Now that we have a working Nova installation, we need to ready it for use by our initial users. This requires us to do some command-line configuration on the Nova controller (or the server with the database). First, we will add a user, then upload a virtual disk image, launch the instance, and finally configure network access for it.

# unzip nova.zip Archive: nova.zip extracting: novarc extracting: pk.pem extracting: cert.pem extracting: cacert.pem # . ./novarc
While not necessary, you might want to view novarc to find out what environmental variables it is setting for you. Remember that you will need to source this file in every session if you want to access your Nova ...
