Abstract
A machine readable policy generated from a policy specification may be obtained. The machine readable policy may specify an exit reason for a virtual processor (vCPU) to exit execution on a host computing system and a set of register access permissions associated with the exit reason. Upon the vCPU exiting for the exit reason, a separation kernel that separates the hypervisor executing on the host computing system from direct hardware access applies the machine readable policy. Applying the machine readable policy includes determining that the hypervisor is requesting access to a register associated with the vCPU, evaluating the access against the set of register access permissions, and allowing the hypervisor to access the register based on the evaluation.
