When the VNC graphics server is enabled through libvirt, QEMU will redirect the graphics output to its inbuilt VNC server implementation. The VNC server will listen to a network port where the VNC clients can connect.

The following screenshot shows how to add a VNC graphics server. Just go to Virtual Machine Manager, open the settings of your virtual machine, and go to the Display Spice tab on the left-hand side:

Figure 6.12 – VNC configuration for a KVM virtual machine

When adding VNC graphics, you will be presented with the options shown in the preceding screenshot:

Type: The type of the graphics server. Here, it is VNC server.
Address: VNC server listening address. It can be all, localhost, or an IP address. By default, it is Localhost only.
Port: VNC server listening port. You can either choose auto, where libvirt defines the port based on the availability, or you can define one yourself. Make sure...
