Nova Command

This is a wrapper nova command provided by cloudmesh which in turn calls the openstack nova command on the target cloud. This also provides you with the capability of setting the target cloud. However, we recommend not using the command and instead use the cloudmesh command sas they allow for information caching

The manual page of the nova command can be found at: Nova

Setting the Target Cloud

You may set the target cloud on which the nova command should run as follows:

.. prompt:: bash, cm>

    nova set india


india is set

Note that if you do not set a target cloud, default cloud considered is 'india'.

Getting the Cloud Info

You may get the cloud info in the following manner:

.. prompt:: bash, cm>

    nova info

By default it gives the 'india' cloud info. To check for specific cloud, here is an example for kilo cloud:

.. prompt:: bash, cm>
