[Qemu-devel] How does QEMU kernel receive any input events from host OS

[Amey Moghe]

Hello all,

I am new to QEMU.While reading about qemu , I came across one
statement: "QEMU does not depend on the presence of graphical output
methods on the host system. Instead, it allows one to access the screen
of the guest OS via VNC. It can also use an emulated serial line,
without any screen, with applicable operating systems." on following
link :

http://en.wikipedia.org/wiki/QEMU

So
please can anybodys tell me how does qemu use VNC server for receiving events and if yes
then how does it receive events from host OS? Or is there any other way
with which QEMU receives input events from host OS?
