Status Power State and dependencies in billing of instance VMs on 3Engines Cloud[🔗](#status-power-state-and-dependencies-in-billing-of-instance-vms-on-brand-name "Permalink to this headline")
|
|
=================================================================================================================================================================================================
|
|
|
|
In 3Engines, instances have their own Status and Power State:
|
|
|
|
> * **Status** informs about the present condition of the VM, while
|
|
> * **Power** states tell us only whether virtual machines are running or not.
|
|
|
|
|
|
|
|
There are six Power states, divided into two groups, depending on whether the VM is running or not.
|
|
|
|
