Abstract:
A plurality of virtual domains are isolated from one another by a virtual machine monitor (VMM), the plurality of virtual domains including a first guest domain and a privileged domain. Peripheral related instructions are isolated from the first guest domain. The privileged domain is to cause execution of the peripheral related instructions, where the peripheral related instructions upon execution validate a type of the peripheral device.
