<title>Importing an Instance: Overview of Events</title>
<body>
<p>The following describes the sequence of events when you import an instance from <ph conkeyref="vbox-conkeyref-phrases/oci"/>.</p>
<ul>
<li>
<p>A custom image is created from the boot volume of the instance.</p>
</li>
<li>
<p>The custom image is exported to an <ph conkeyref="vbox-conkeyref-phrases/oci"/> object and is stored using Object Storage in the bucket specified by the user.</p>
</li>
<li>
<p>The <ph conkeyref="vbox-conkeyref-phrases/oci"/> 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.</p>
</li>
<li>
<p>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 <ph conkeyref="vbox-conkeyref-phrases/product-name"/>.</p>
</li>
<li>
<p>A new VM is created using the VMDK image for the cloud instance.</p>
<p>By default, the new VM is not started after import from <ph conkeyref="vbox-conkeyref-phrases/oci"/>.</p>
</li>
<li>
<p>The downloaded TAR archive is deleted after a successful import.</p>
</li>
</ul>
