nova

nova

The nova client is the command-line interface (CLI) for the Compute service (nova) API and its extensions.

This chapter documents nova version 9.0.1.

For help on a specific nova command, enter:

$ nova help COMMAND

Note

Over time, command line functionality will be phased out of the nova CLI and into the openstack CLI. Using the openstack client where possible is preferred but there is not full parity yet for all of the nova commands. For information on using the openstack CLI, see:

https://docs.openstack.org/python-openstackclient/latest/

Locale encoding issues

If you encounter an error such as:

UnicodeEncodeError: 'ascii' codec can't encode characters in position

The solution to these problems is different depending on which locale your computer is running in.

For instance, if you have a German Linux machine, you can fix the problem by exporting the locale to de_DE.utf-8:

export LC_ALL=de_DE.utf-8
export LANG=de_DE.utf-8

If you are on a US machine, en_US.utf-8 is the encoding of choice. On some newer Linux systems, you could also try C.UTF-8 as the locale:

export LC_ALL=C.UTF-8
export LANG=C.UTF-8

<server>
Name or ID of server.

--length <length>
Length in lines to tail.
