In order to resolve the question, 'how will the guest
operating system tell the host operating system that
the unattended install process finish', we took the
simple approach and created a simple socket communication
ack process: The test instantiates a server tcp socket
on port 12323, and waits during a specified amount of time.
For guests, the vast majority of the unattended install
processes can deal with executing commands at the end of
the install process. Let's take advantage of that and
make clients tell the server about the end of the process
using simple programs that can do that. The implementation
of that strategy varies trough different operating systems.
This is the kvm test implementation code, client programs
will follow on later patches.
