Abstract
Systems and methods for embedding emulation support for a hardware feature into a virtual machine to enhance the security of the hypervisor and host system. An example method may comprise: receiving, by a processing device executing a hypervisor, a message indicating a hardware feature is unavailable; determining, by the hypervisor, whether a virtual machine is capable of emulating the hardware feature; and causing, by the hypervisor, the virtual machine to emulate the hardware feature in response to determining the virtual machine is capable of emulating the hardware feature.
