You can use VirtualBox Manager to control a cloud VM as follows:
Start. Use the Start button in the VirtualBox Manager toolbar.
Stop. Right-click on the cloud VM name, to display the Close menu. Options to shut down and power off the cloud VM are available.
Terminate. Use the Terminate button in the VirtualBox Manager toolbar.
This action deletes the instance from Oracle Cloud Infrastructure.
When you control a cloud VM in VirtualBox Manager the machine list is updated automatically with the current instance state, such as Stopped or Running.
When you control an instance using the Oracle Cloud Infrastructure console, VirtualBox Manager updates the status for the corresponding cloud VM automatically.
