<title>Create image (nova)</title>
|

<para>You can use the nova client to list images, set and delete
|
|
image metadata, delete images, and take a snapshot of a
|
|
running instance to create an image.</para>
|
|
<para>The safest approach is to shut down the instance before you
|
|
take a snapshot.</para>
|
|
<para>You cannot create a snapshot from an instance that has an
|
|
attached volume. Detach the volume, create the image, and
|
|
re-mount the volume.</para>
