There is a controller machine(called machine A), and a target
machine(called machine B).
We can use  A to load a image to B. And then in B, start an installer
process and web server.
User can use browser in another machine to get access this server,choose
some installation
parameters.The web server records the parameters and send them to the
installer process.
So that will realize the installation.

several accesses to web
server, the parameters may be affected. We just want to one user to do the
installation process.
