Virtual Device Interfaces
provide a standardway to publish interfaces of virtual devices by a software component
this enables other software componentts to interact with these devices
渲染render its output accordidng
to be processed by the back-end
in addition many other interface type can be expose by the back-end
the back-end exposes interface like display output
mouse input
it is also possible for the back-end to dynamically switch front-ends improve back-end usability and flexibility
better sharing of development maintenance and overall product quality;;

spice server is implemented as a VDI front-end and the spice-QEMU provides back-end interfaces;
make an offort to push this specification forward in order to benefit all;
