VNC

VNC (Virtual Network Computing) is a system for remote access to a computer's desktop. VNC allows you to send keyboard keystrokes and mouse movements from one computer to another, and to relay screen content over a computer network.

VMmanager uses VNC to remotely manage virtual machines (VMs).

Connecting to a VM via VNC

You can connect to a VM:

• through the platform interface;
• using a third-party VNC client. For example, RealVNC Viewer or TightVNC .

Connecting from the VMmanager interface

1. Enter Virtual machines → select the VM → menu → VNC . The VM desktop opens in a new browser tab.
2. Enter the login and password to connect to the VM.

Connecting with a VNC client

To create a connection, you will need to specify the VNC server details: address, connection port and password. This data can be viewed in the virtual machine card: Virtual machines → select the VM → VNC settings tab.

Connection example for RealVNC Viewer:

1. Download and install the version of RealVNC VIewer for your operating system.
2. Start RealVNC Viewer and create a connection to the VM:
   1. Enter File → New connection .
   2. In the VNC Server field, enter the IP address and port of the VNC server, separated by a colon.
   3. In the Name field, enter an arbitrary name for the connection.

   4. Press OK .

      
3. To connect to a VM, double-click the connection icon.
   
4. If RealVNC VIewer displays a warning about an unsecured connection, press Continue .
   
5. In the Password field, enter the password for the VNC server and press OK .
   
6. Enter the login and password to connect to the VM.

Possible connection issues

If the VM was suspended and then resumed:

• existing VNC connections may be terminated. It is recommended to create a new connection;
• when connecting for the first time, messages such as the following may appear in the system log

  clocksource: timekeeping watchdog on CPU0: Marking clocksource 'tsc’ as unstable because the skew is too large:
  tsc: Marking TSC unstable due to clocksource watchdog

  Ignore these messages and press Enter in the connection window.
