Nova Quickstart

The contrib/novascript.sh file in the source distribution is a script that will quickly set up nova to run on a single machine. It is tested against Ubuntu only, but other distributions are forthcoming.

Usage

Unless you want to spend a lot of time fiddling with permissions and sudoers, you should probably run nova as root.

sudo -i

If you are concerned about security, nova runs just fine inside a virtual machine.

Use the script to install and run the current trunk. You can also specify a specific branch by putting lp:~someone/nova/some-branch after the branch command

./nova.sh branch
./nova.sh install
./nova.sh run

The run command will drop you into a screen session with all of the workers running in different windows You can use eucatools to run commands against the cloud.

euca-add-keypair test > test.pem
euca-run-instances -k test -t m1.tiny ami-tiny
euca-describe-instances

To see output from the various workers, switch screen windows

<ctrl-a> "

will give you a list of running windows.

When the instance is running, you should be able to ssh to it.

chmod 600 test.pem
ssh -i test.pem root@10.0.0.3

When you exit screen

<ctrl-a> <ctrl-d>

nova will terminate. It may take a while for nova to finish cleaning up. If you exit the process before it is done because there were some problems in your build, you may have to clean up the nova processes manually. If you had any instances running, you can attempt to kill them through the api:

./nova.sh terminate

Then you can destroy the screen:

./nova.sh clean

If things get particularly messed up, you might need to do some more intense cleanup. Be careful, the following command will manually destroy all runnning virsh instances and attempt to delete all vlans and bridges.
