It depends which commad i am executing. Dump memory is resource intesive but commds like read the process list shoudn't cost to much performance.
The problem is that the usershould be able to choose wich command is executed. So i must add a possibility to get this command to the driver. Or am i thinking wrong?

Tobias

Is your command very resource-intensive?
I'm thinking that maybe you could just add your commands to the periodic VM monitorization. Or add a flag somewhere to indicate if the operation should be done in the next poll action... If you avoid to change the OpenNebula code it will be easier to distribute, use with newer versions, etc.

Hi,thank you for your quick answer!I am executing a volatility command on the driver. Results are some kind of lists or process information which is show directly on the screen/shell.At the moment i added functionality to one.vm.action to process my commands. Which part would be best to save the results in a document ressource or add it to the vm template?How can i invoke this?Regards,Tobias2013/3/25 Carlos Martín Sánchez <[email protected]>Hi,What kind of results will you present to the user?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...Regards[1] http://opennebula.org/documentation:rel3.8:api#actions_for_document_management--

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!Best Regards,Tobias
