Change subject: core, webadmin: Support diskless snapshots ...................................................................... core, webadmin: Support diskless snapshots This patch removes the restriction on a diskless VM, in order to align the behavior with the current partial behavior - currently, you can create a VM with a single disk, take a snapshot, and then remove the disk from all the snapshots, leaving the snapshot diskless. In the backend: The code that finalizes the preview was extracted into a method, which is now called from two places: * If the snapshot has disks, it's called from EndSuccessfully(), after all the disks have been previewed. This is not a behavior change - the code that was there was simply extracted to a method. * If the snapshot does not have any disks, it's called at the end of the ExecuteVmCommand, since there are no async tasks that we're waiting for. In the frontend: * The restriction on taking a snapshot of a diskless VM was removed.
