Access an instance through a console
|
|
====================================
|
|
|
|
VNC or SPICE is used to view the console output of an instance, regardless of
|
|
whether or not the console log has output. This allows relaying keyboard and
|
|
mouse activity to and from an instance.
|
|
|
|
There are three remote console access methods commonly used with
|
|
OpenStack:
|
|
|
|
novnc
|
|
An in-browser VNC client implemented using HTML5 Canvas and
|
|
WebSockets
|
|
|
|
spice
|
|
A complete in-browser client solution for interaction with
|
|
virtualized instances
|
|
|
|
xvpvnc
|
|
A Java client offering console access to an instance
|
|
|
|
Example:
|
|
|
|
To access an instance through a remote console, run the following
|
|
command:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack console url show INSTANCE_NAME --xvpvnc
|
|
|
|
The command returns a URL from which you can access your instance:
|
|
|
|
.. code-block:: console
|
|
|
|
+--------+------------------------------------------------------------------------------+
|
|
| Type | Url |
|
|
+--------+------------------------------------------------------------------------------+
|
|
| xvpvnc | http://192.168.5.96:6081/console?token=c83ae3a3-15c4-4890-8d45-aefb494a8d6c |
|
|
+--------+------------------------------------------------------------------------------+
|
|
|
|
:option:`--xvpvnc` can be replaced by any of the above values as connection
|
|
types.
|
|
|
|
When using SPICE to view the console of an instance, a browser plugin
|
|
can be used directly on the instance page, or the
|
|
:command:`openstack console url show` command can be used with it, as well, by
|
|
returning a token-authenticated address, as in the example above.
