FlexVM suite allows to pause a running Guest. By "pausing" we mean pausing the Guest process in a state we can recover through the opposite proces "resume".
This action does not dump the memory content to the disk, so RAM and CPU resources can still being reserved. It is an nimediate action.
In order to pause a Guest, select it and open the drop-down menu. Choose the "Pause" option.
The Guest will immediately change its icon, showing it has gone from running state (
) to pause state (
).
