Hi all,
These are what I did (nova version is 'Essex'):
1. logon the instance
2. shutdown it using 'shutdown -h now'
3. wait a few minutes until the instance's vm_state, power_state change to
'shutoff', '5' respectively
4. run cmd 'nova image-create <server> <name>' to snapshot the server instance
5. the instance's vm_state changes to 'active', but the power_state doesn't
change(still '5')
My questions:
1. Can we create a snapshot with a 'shutoff' instance?
2. If we can do the above operation, what is the correct vm_state after it?
still 'shutoff' or changes to 'active'?
3. I also saw the source codes in
nova/nova/compute/manager.py:snapshot_instance(), the vm_state is update at
first by
self._instance_update(context,
instance_ref['id'],
power_state=current_power_state,
vm_state=vm_states.ACTIVE)
and the task_state is changed to 'None' finally
self._instance_update(context, instance_ref['id'],
task_state=None)
should we change back the vm_state like this, too?
Thanks in Advance
Best Regards,
Wangpan_______________________________________________
