Configuring VNC for VM Login

Configuring VNC for VM Login


The virtual environment provides the Virtual Network Computing (VNC) service that allows the VNC viewer (controlling end) to control the VNC server (controlled end). You can use the VNC viewer to control the VNC server, run applications on the VNC server, and use system resources of the VNC server.

You can log in to a VM (controlled end) from the VNC viewer using the IP address of a virtual interface and the VNC service port number, and install the operating system (OS) and applications on the VM in the GuestOS graphical user interface (GUI).


To ensure secure login using VNC, you are advised to establish an IPSec tunnel on the VNC client to encrypt data.
