Abstract
A controller sandbox using an emulation framework of a hypervisor is disclosed. A hypervisor receives, from a task in a virtual machine that is controlled by the hypervisor in a computing device on which the hypervisor executes, a first implement device command request that requests that a first device command be implemented on a controllable device communicatively connected to the computing device via an interface. The hypervisor determines that the first device command is on an authorized device command list. Based on determining that the first device command is on the authorized device command list, the hypervisor communicates a signal to the controllable device to implement the first device command.
