Hi,

I’m currently developing an application that has to communicate with OpenNebula,  
the official documentation that I found is very light and doesn’t really explain how to boot a VM from  
an image and a template, destroy it, etc.  
Can someone has a good source of documentation or explanation ?

Thanks 😄

Documentation I found:  
[http://docs.opennebula.org/4.10/integration/system\_interfaces/ruby.html](http://docs.opennebula.org/4.10/integration/system_interfaces/ruby.html)

> **[OpenNebula Cloud API 4.10](https://docs.opennebula.io/doc/4.10/oca/ruby/)**

And the github of the official RUBY API

Apart from those you can take a look to the onevm command, but the examples  
in [http://docs.opennebula.org/4.12/integration/system\_interfaces/ruby.html](http://docs.opennebula.org/4.12/integration/system_interfaces/ruby.html)  
should be enough to start.

Just a tip to create a VirtualMachine object for specific VM use:

vm = OpenNebula::VirtualMachine.new\_with\_id(id, client)

Then you can use the virtual\_machine methods with the vm object.
