Abstract
Access to virtual machine inputs and outputs are controlled. Controlling access to virtual machine inputs and outputs may comprise locking inputs and outputs of a virtual machine from within the virtual machine, other than a predefined limited access input, detecting a request to unlock the inputs and outputs of the virtual machine; determining if a requester is authorized to unlock the inputs and outputs of the virtual machine and unlocking, temporarily, the inputs and outputs of the virtual machine if the requester is authorized. The predefined limited access input is configured to receive an input device with a private secret for unlocking the inputs and outputs of the virtual machine. The inputs and outputs are unlocked when an input device having a shared password is attached.
