This is a simple client for connecting to the remote serial console of an OpenStack Nova server, using the API implemented in the Juno release of OpenStack. You can read more about that support here:

• http://blog.oddbit.com/2014/12/22/accessing-the-serial-console-of-your-nova-servers/

With valid OpenStack credentials (OS_USERNAME, OS_PASSWORD, OS_AUTH_URL, etc) available in your environment, you can run novaconsole with the name or UUID of a Nova server:

$ novaconsole my-server
WARNING:novaconsole.client:connected to: ws://127.0.0.1:6083/?token=bdcea854-2566-4f3b-86ef-4791aba42eea
WARNING:novaconsole.client:type "~." to disconnect

You can also provide a websocket URL directly on the command line:

$ novaconsole --url ws://127.0.0.1:6083/?token=bdcea854-2566-4f3b-86ef-4791aba42eea
WARNING:novaconsole.client:connected to: ws://127.0.0.1:6083/?token=bdcea854-2566-4f3b-86ef-4791aba42eea
WARNING:novaconsole.client:type "~." to disconnect

In either case, you will have an interactive connection to the serial console of your Nova server. You can type ~. to disconnect. If you find that the ~ conflicts with something (for example, ~ is also used as the default escape character by ssh), you can specify a new escape character with -e:

$ novaconsole -e@ my-server
WARNING:novaconsole.client:connected to: ws://127.0.0.1:6083/?token=3fd11349-cd64-4dac-bbe0-68c49e9e1dc9
WARNING:novaconsole.client:type "@." to disconnect

For this to work, your server must be configured to support serial console access. This is a typical default for most "cloud" specific images, which will include something like console=tty0 console=ttyS0,11500n81 on the kernel command line. This provides console output on both the graphical (vnc) console and the serial console, and takes input from the serial console.

You can install the package with pip:

pip install git+http://github.com/larsks/novaconsole.git

Or you can clone the repository by hand and run setup.py:

git clone http://github.com/larsks/novaconsole.git
cd novaconsole
python setup.py install
