6109R: KVM support added

We just added KVM support to Aventurin{e} 6109R.

At this time the Qemu KVM support for Aventurin{e} 6109R is still a bit rudimentary.

However: It's possible to create a VM via the GUI, to install the OS into that VM via an ISO image from the directory /vz/ISOs/ and then use VNC to manage the installation of the OS.

Once a VM has been created, only its basic settings can be administered via the GUI, but the whole host of configuration options can still be performed from the command line.

Please note:

As is we're not recommending to use Aventurin{e} 6109R to run more than the occasional test VM. The preferred virtualization method should be CT (Container). 

In our experience using Aventurin{e} 6109R with Qemu VMs dramatically slows down the handling of the node.
