Debugging and Configuring your dedicated server(s) via VNC

What is the vKVM - system?
The vKVM Rescue System (Virtual Keyboard / Video / Mouse) is an extension of the existing Rescue system which loads a Linux system using PXE in the memory of your server. With the vKVM Rescue System starts a rescue system that is installed on your server operating system to boot in a virtual machine. The graphical output of the virtual machine is transmitted here via a SSL-secured VNC connection, so you have the opportunity to work on your operating system, "as if" you were sitting right in front of the server.
vKVM automatically detects your hard drive so you can boot into the BIOS vKVM it. Further, the CPU of the server is virtualized in VM. Furthermore, the VM emulates a network card, providing you with the ability to access the internet within the VM.

To start vKVM you have to do is log in to the Customer Center, select your server in the left menu and select the contract "Rescue system". Now select the entry "vKVM" and activate the rescue system. After some time vKVM is available and you can log in using VNC client.
