The commands that trigger a driver action are asynchronous, so you can't get any result immediately to the user. If you are modifying the c++ core, you could add your custom information in the VM template, this way the users will see it in the 'onevm show' output. Or you could use the generic document resources [1]. These are just like the templates managed with onetemplate; they will store anything and will also have owner, group, acl, permissions...

For my practical part I decided to add forensic services to open nebula. So i extended the onevm commad and added a function forensics. I extended the whole way through the code. At the moment i am able to execute my own vmmd script, in which a forensic tool (volatility) is called and analyse the virtual machines. But now I don't know how to get the result back to the user. Basically i want to create a scenario like this: A user just puts in onevm forensics id and the analysis result is shown to him in the screen. Anybody can help me here and tell me what funtions to call or how the way back to the user shell works? Does anyone have experience with adding funtions and the flow of commands through the code? THX!
