To gain access to a virtual machine's (VM) Virtual Network Computing (VNC) console, a SSH tunnel from the local machine through the API endpoint to the node hosting the VM has to be created. Once the SSH tunnel is created, a VNC client is then launched on the local machine and connects to a specific local port. Each VM's SSH connection has a specific user, port and SSH keys.
There are two methods of creating the SSH tunnel—downloading the VNC key information and manually setting up SSH port forwarding, or downloading a JNLP file that creates the SSH connection and starts a VNC client.
