<DIV><FONT color=#000000 size=3 face=宋体>Hi all,</FONT></DIV>
<DIV><FONT color=#000000 size=3></FONT> </DIV>
<DIV><FONT color=#000000 size=3>These are what I did (nova version is
'Essex'):</FONT></DIV>
<DIV><FONT color=#000000 size=3>1. logon the instance</FONT></DIV>
<DIV><FONT color=#000000 size=3>2. shutdown it using 'shutdown -h
now'</FONT></DIV>
<DIV><FONT color=#000000 size=3>3. wait a few minutes until the instance's
vm_state, power_state change to 'shutoff', '5' respectively</FONT></DIV>
<DIV><FONT color=#000000 size=3>4. run cmd 'nova
image-create <server> <name>' to snapshot the server
instance</FONT></DIV>
<DIV><FONT color=#000000 size=3>5. the instance's vm_state changes to 'active',
but the power_state doesn't change(still '5')</FONT></DIV>
<DIV><FONT color=#000000 size=3></FONT> </DIV>
<DIV><FONT color=#000000 size=3>My questions:</FONT></DIV>
<DIV><FONT color=#000000 size=3>1. Can we create a snapshot with a
'shutoff' instance?</FONT></DIV>
<DIV><FONT color=#000000 size=3>2. If we can do the above operation, what is the
correct vm_state after it? still 'shutoff' or changes
to 'active'?</FONT></DIV>
<DIV>3. I also saw the source codes in
nova/nova/compute/manager.py:snapshot_instance(), the vm_state is update at
first by</DIV>
<DIV> self._instance_update(context,<BR>
instance_ref['id'],<BR>
power_state=current_power_state,<BR>
<FONT color=#000000>vm_state=vm_states.ACTIVE</FONT>)</DIV>
<DIV> and the task_state is changed to 'None' finally</DIV>
<DIV>
self._instance_update(context, instance_ref['id'], <FONT
color=#000000>task_state=None</FONT>)</DIV>
<DIV> should we change back the vm_state like this, too?</DIV>
<DIV> </DIV>
<DIV>
<DIV>Thanks in Advance<BR><BR>Best Regards,</DIV>
