6.6.3. Logging in to Virtual Machines with VNC
VNC is a supported display protocol for Linux and Windows virtual machines in the Administration Portal. The advantage of using VNC is that you do not have to install additional SPICE plugins. However, bear in mind that VNC is not supported in the User Portal. If your virtual machines are to be used in the User Portal, do not set VNC as the machine's default display protocol.
If you have already set your virtual machine's display protocol to VNC when you created it, you can click the Console button to log in to it. If your virtual machine's display protocol is set to SPICE, and you would like to change it to VNC, use the following procedure.
