Description Michael Grandjean univentionstaff 2017-06-28 22:37:57 CEST
Feature Request during technical training:

When starting a VM via the "Play" (Start) button in the grid, this button disappears (and a "Monitor" (View) button to start a VNC connection appears right next to it).
The attendees expected that the "Play" button would change to a "Pause" button.

Although I agree that this would be expected behaviour, I am not sure which action a "Pause" button should actually take. Should it really pause the VM or better suspend or shutdown or even poweroff?
A short survey with the attendees showed a majority for pause.

The functionality to show buttons was not ported to UCS-3 and got dropped with git:fc437c958e9786e6d00674192d166436b1449da6.

We don't show any pause/stop button as there are too many cases:
- just pause the VM (just does not get CPU time anymore but stays in RAM)
- graceful shutdown (notify the guest to shut down)
- forced shutdown (pull the plug and loose all runtime state)
- remove (throw away everything including the persistent data like HD)
Because of that we only show those actions in the context menu.
