Watnuss, You can refer to class Request.java (and related) from package com.cloud.agent.transport, project core. It uses a library 'Gson' to convert commands into Json.
About how management server chooses host, simply speaking, each command is sent to the host which should do the job, e.g. for KVM, a StartCommand for a specified VM is sent to the host that VM runs on.

What I am particular interested in is, where and how the JSON object are created and how they look like. (The first step would be in which package/file is the JSON file created? Couln't find yet) What I am also interested in is how the management server chooses the host. As I assume from the log files it sends keep-alives to the management server? It would be really great if you could give me a hand with these questions Best regards Watnuss
