Hi This problem is as described by Ondra becasue of a kind of race condition between the boot process and the monitor probes. You may or may not see it depending on timing network and the like.
OpenNebula 4.10.2 includes some logic to deal with this and also to recover automatically the VM when its again monitored. What version are you running?
