VMware Workstation 4.5
The suspend and resume feature is most useful when you want to save the current state of your virtual machine, then pick up work later with the virtual machine in the same state it was when you stopped.
Once you resume and do additional work in the virtual machine, there is no way to return to the state the virtual machine was in at the time you suspended.
To preserve the state of the virtual machine so you can return to the same state repeatedly, take a snapshot. For details, see Using the Snapshot.
The speed of the suspend and resume operations depends on how much data has changed while the virtual machine has been running. In general, the first suspend operation takes a bit longer than later suspend operations do.
