Hi,

a question for the training session students (I have always this question in other sessions)


Why the behaviour of stop/shutdown of a vm is different when HA is enabled ?


without HA:

 shutdown : acpi shutdown  --> vm is stopped
 stop     : process killed  ---> vm is stopped


with HA:
 shutdown : acpi shutdown --> vm is stopped and restarted because HA is still enabled
 stop     : acpi shutdown -> vm is stopped and ha is disabled


this is really strange to call acpi shutdown when stopping the vm.


What we expect with HA : 

shutdown : acpi shutdown  --> HA is disabled--> vm is stopped 
 stop    : process killed  ---> HA is disabled --> vm is stopped
