The following describes the sequence of events when you import an instance from Oracle Cloud Infrastructure.

• A custom image is created from the boot volume of the instance.

• The custom image is exported to an Oracle Cloud Infrastructure object and is stored using Object Storage in the bucket specified by the user.

• The Oracle Cloud Infrastructure object is downloaded to the local host. The object is a TAR archive which contains a boot volume of the instance in QCOW2 format and a JSON file containing metadata related to the instance.

• The boot volume of the instance is extracted from the archive and a new VMDK image is created by converting the boot volume into the VMDK format. The VMDK image is registered with Oracle VM VirtualBox.

• A new VM is created using the VMDK image for the cloud instance.

  By default, the new VM is not started after import from Oracle Cloud Infrastructure.

• The downloaded TAR archive is deleted after a successful import.
