[one-users] How does opennebula monitor the vm's state?

[cmcc.dylan]

Hi, everyone!
    As we know, opennebula defines vm's life-cycle state, for example: RUNNING,UNKNOWN. I have some questions about vm's life-cycle state.
1. I find a problem that when vm's state becomes unknown , after that, even though the vm becomes right, the vm's state will keep unknown all the time.
2. opennebula uses what way to judge the vm's state when it executes monitoring action. for example, which funtions used in opennebula source code.


look forward to some helps!
