Enhancements and bug fixes for v4.7.1-leaseweb13-1 (2017-07-19)

noVNC console

Our new noVNC console will be available for all Apache CloudStack Private Cloud customers. 

noVNC is a browser based VNC client implemented using HTML5 technologies (Web Sockets, Canvas) with encryption (wss://) support.

Key features include: 

  • Better browser compatibility — noVNC is a HTML5 VNC client that runs well in any modern browser including mobile browsers (iOS and Android)

  • Websockets for persistent connections

  • Overall more responsive performance

As a user you can also use the clipboard functionality to paste information in the console, and access your machine in real time with better performance.

This new console replaces a current solution that is based on a non-persistent connection. This shift is in part meant to address an occasional sluggish user experience that could result from a lack of a persistent connection.

What you do with new noVNC console

The remote console works as a "virtual terminal", almost like a computer screen attached to a server, that you can use to interact with your operational system using your keyboard and mouse.

You can use it when you need to install (and/or configure) your favorite remote access method, such as SSH or RDP, that offers more features than the remote console itself.

You can also use it if, for any reason, you are no longer capable of accessing the server through any other method.

How to setup the console

Perform the following steps to set up the noVNC console:

  1. Go to the left panel and click “Instances”.
  2. On the “Instances” page on the right, click the instance name, for which you wish to access the Console.
  3. You will the see the “Details” tab as it appears on the screenshot below.
  4. Click on the  “View console” icon — the last one on the right.
  5. The “Console view” will open in a separate window and will display what you see on the screenshot below.

  6. Hit “Enter” to activate the screen and then enter your credentials to gain access to the Console.
    Now you are ready to use it.

If you have any questions regarding this upgrade, or you are experiencing any problems, our engineers are available via support@leaseweb.com.

noVNC is an opensource project that is also used by both cloud platforms like Openstack, OpenNebula, and a number of cloud providers.

Later this year the Cloudstack team at Leaseweb will be happy to release it to the Apache CloudStack community as well.
