The VNC console for OVM 2.2 doesn’t work out of the box. You need to add a few component so that your can manage your environment using TightVNC.
You may have noticed that when you clicked on the VNC Port to connect to VM, you received “load: class VncViewer.class not found”
This is because the tightvnc and ovm-console components aren’t installed by default.
To fix:
goto http://oss.oracle.com/oraclevm/manager/RPMS/ and download / install
ovm-console-1.0.0-2.i386.rpm
tightvnc-java-1.3.9-3.noarch.rpm
This allows IE and Chrome browser connections to manage Oracle Virtual Machines.
