Image actions

Several actions are applicable to virtual machine images. You can create, download, revert, master, unmaster, and snapshot images.

Underneath, the icons of these actions are depicted.

Clone Creates a clone of the image.
  Downloads the image.
Revert Revert image to snapshot.
Master Marks QEMU (qcow2) images as a master image.
Unmaster Unmasters the image, i.d., the image stops being a master image. Unmaster is only possible if no images are using the master image.
Snapshot Takes a snapshot of the image. You can have one snapshot.
Unsnap Removes the snapshot.
