Discard the saved state of a virtual machine.
The VBoxManage discardstate command discards the saved state of a virtual machine (VM) that is not currently running. This command causes the VM's operating system to restart the next time you start the VM.
Where possible, avoid performing this action. The effects of this command are equivalent to unplugging the power cable on a physical machine.
uuid|vmnameSpecifies the Universally Unique Identifier (UUID) or name of the VM.
