If booting from an ephemeral disk

the OpenStack Command Line Clients can be used with the command:

[name@server ~]$  openstack server image create <server-name>

where <server-name> should be replaced with the name of your server. This action will only include the VM's root drive (e.g. /dev/vda) in the image. Ephemeral drives and non-boot attached volumes will not be included in the image so additional measures should be taken to preserve this data. In addition, if the VM is writing to disk while the image is being created the filesystem may be captured in an inconsistent state. We recommend the VM be shut off (not deleted) before an image is created from it.
