I'd like to ask for better understanding of your instance states.
Why DC cannot stop the instance but only destroy? (I see that EC2's destroying instance when it's stopped, but seems that it doesnt destroy EBS instance)
When I reboot instance via AWS, I see the state 'Rebooting' in GUI, but in DC EC2 driver I dont see that state, any reason for that?
Why RHEVM driver doesnt have set transition from stopping to stopped?
