Checking out Virtual Device Interfaces

Loaded the spice server software as the VDI front end. Check back for more info…

Here is the partial specifications from the paper:

“Virtual Device Interfaces (VDI) provide a standard way to publish
interfaces of virtual devices by a software component. This enables
other software components to interact with these devices. Going
forward, the first component will be called the back-end and the second
component will be called the front-end. An example for using Virtual
Device Interfaces is as part of a virtual machine system, where the
back-end will be the hardware emulation layer. The back-end will expose
interfaces like display port, mouse input etc. The front-end will plug
into the display output and will render its output according to it's
specific implementation. The front-end will also plug into the mouse
input and send mouse events to be processed by the back-end. In
addition many other interface types can be exposed by the back-end.
Another example of back-end is a remote display system in a physical
machine environment. Here, the back-and is implemented using known
techniques for interacting with the native OS for the purpose of
receiving display updates and pushing inputs. The back-end exposes
interfaces like display output, mouse input etc. The front-end can be
exactly the same as in the previous example.

By using VDI one back-end an use many types of front-ends without any
special code modification. It is also possible for the back-end to
dynamically switch front-ends, and improve back-end usability and
flexibility. The use of front-ends by many back-ends allows for a
better sharing of development, maintenance, and overall product
quality.”
