Restore a Snapshot
To return a virtual machine to its original state, you can restore a snapshot.
Do one of the following:
Procedure
n
The Inventory > Virtual Machine > Snapshot menu contains the command Revert to Snapshot.
n
The Snapshot Manager has a Go to button.
Parent Snapshot
The parent snapshot is the most recently saved version of the current state of the virtual machine.
If you have just taken a snapshot, that stored state is the parent snapshot of the current state (You are here). If
you revert or go to a snapshot, that snapshot becomes the parent of the current state (You are here).
The parent snapshot is always the snapshot appearing immediately above the You are here icon in the Snapshot
Manager.
N
OTE
The parent snapshot is not always the snapshot you took most recently.
Revert to Snapshot Command
Reverting snapshots immediately activates the parent snapshot of the current state of the virtual machine.
The current disk and memory states are discarded and restored as they were when you took that snapshot. If
your parent snapshot was taken when the virtual machine was powered off, choosing Snapshot > Revert to
Snapshot moves the powered-on virtual machine to that parent state, that is, to a powered-off state.
If the snapshot was taken while the virtual machine was powered on and the virtual machine settings are set
to revert to snapshot when powering off, the virtual machine moves to a suspended state when it reverts to
the parent snapshot. If the no memory option is set, the virtual machine moves to a suspended state, even if
the revert operation is performed, but not through the powered-off action. If the memory option is set, the
power-off revert action puts the virtual machine in a suspended state. This process is illustrated in
Figure 17-1 .
N
OTE
Virtual machines running certain kinds of workloads might take several minutes to resume
responsiveness after reverting from a snapshot. This delay may be improved by increasing the guest memory.
