The same problem occurs when a (VNC) console is started using the button at the vm details page. It appears that a reconfigure task is started to enable remote display and set a port and password for connecting to the console. The following properties are set during this reconfigure:
When starting a console the 'Reconfigure Complete' email should not be sent because the user has not requested a reconfigure. I see no other solution that to disable all 'Reconfigure Complete' emails by overriding the corresponding automation entry as suggested by @bevans.
I suggest the 'Reconfigure Complete' email functionality to be removed completely from MIQ in the next release because of these issues. Or otherwise these issues should be addressed because the current behaviour is experienced as a bug.
