[one-users] start and shutdoen VMs - no problem, just trying to contribute

[Ruben S. Montero]

Hi Francesco,

Thanks for sharing, I just curious about the sleep statement after the
instantiate command. Is there any timing problems there? Is there anything
that OpenNebula could do better to get rid of the sleep?

Cheers

Ruben
