Along with virtualization technology adopted by both enterprise and customer popularly, virtual machines escape attacking become more and more critical which could NOT be ignored. Because of virtual devices' nature character (virtual device emulation is in host level, guest can access virtual devices with arbitrary data), they are a big attack surface to achieve virtual machine escaping. In fact among those reported virtual machines escape attacking, the virtual device attacking hold big ratio. For example, the VENOM attacking (Reference 8.1).<br><br> Several fuzzing methods towards virtual devices have been released including dump I/O traces and replay in guest OS, conformance fuzzing to constraint virtual device in proper internal state and so forth. However, rare of them considered calculating and controlling code coverage and control in intension. And also, rare of them consider keep their fuzzing framework portable for difference virtualization software.<br><br> So what happens when virtualization fuzzing encounter with AFL? We would like give you one possible answer. Our portable virtual device fuzzing framework with AFL could solve both of the two challenges—code coverage feedback and portability.
