PCA How To Access OVM's Virtual Guest Console Using Vncviewer (Doc ID 2634984.1)

Last updated on JULY 14, 2020

Applies to:

Private Cloud Appliance - Version 1.0.1 and later
Linux x86-64

Goal

This article explains how to connect to virtual machine console using a vncviewer application instead of the console button in the OVM Manager UI, utilizing ssh "tunnels" ("Port Forwarding").

It assumes a "vncviewer" application is installed on the system that is to connect to the virtual machine console.

PCA systems at Version 2.2.2 or lower have OVM Manager 3.2.x. These versions utilize Java to automate the connection; the level of Java incorporated in OVM Manager Version 3.2.x or lower is not compatible with current versions. This prevents the consoles of virtual machines being displayed on desktop systems with current Java levels. Later releases of OVM Manager, such as 3.4.x included with PCA 2.3.x and above, do not use Java for console connection.

The Compute Nodes, by default, are not connected to networks external to the PCA system. Thus to reach the compute node one must first connect to a node that does have access. In the examples below, a management node is used for this.
