There are several methods to interact with the VNC console, using a VNC client directly, a special java client, or through the web browser. For information about configuring the console, see .

Nova enables you to create access_urls through the os-consoles extension. Support for accessing this URL is provided by the nova client: $ nova get-vnc-console [server_id] [novnc|xvpvnc] Specify 'novnc' to get a URL suitable for pasting into a web browser. Specify 'xvpvnc' for a URL suitable for pasting into the Java client. To request a web browser URL: $ nova get-vnc-console [server_id] novnc

To enable support for the OpenStack Java VNC client in compute, run the nova-xvpvncproxy service. xvpvncproxy_port=[port] - port to bind (defaults to 6081) xvpvncproxy_host=[host] - host to bind (defaults to 0.0.0.0) As a client, you need a special Java client, which is a slightly modified version of TightVNC that supports our token auth: $ git clone https://github.com/cloudbuilders/nova-xvpvncviewer $ cd nova-xvpvncviewer/viewer $ make To create a session, request an access URL by using python-novaclient. Then, run the client as follows. To get an access URL: $ nova get-vnc-console [server_id] xvpvnc To run the client: $ java -jar VncViewer.jar [access_url]

Retrieving an access_url for a web browser is similar to the flow for the Java client. To get the access URL, run the following command: $ nova get-vnc-console [server_id] novnc Paste the URL into your web browser. Additionally, you can use the OpenStack dashboard, known as horizon, to access browser-based VNC consoles for instances.
