You can restore the parent snapshot of the current state of the virtual machine.

When you revert to a snapshot, disks that you added or changed after the snapshot was taken are reverted to the snapshot point. For example, when you take a snapshot of a virtual machine, add a disk, and revert the snapshot, the added disk is removed.

Required privilege: Virtual machine.Snapshot management.Revert to snapshot on the virtual machine.

Right-click a virtual machine in the vSphere Client inventory and select Revert to Current Snapshot.

The virtual machine power and data states are returned to the states they were in at the time you took the parent snapshot. If the parent snapshot is a memory snapshot, the virtual machine is restored to an on power state.
