SimpleVisor is a simple, portable, Intel VT-x hypervisor with two specific goals: using the least amount of assembly code (10 lines), and having the smallest amount of VMX-related code to support dynamic hyperjacking and unhyperjacking (that is, virtualizing the host state from within the host). It works on Windows and UEFI.
In ShvVpInitialize, there is a branch checking for SHV_STATUS_SUCCESS, added in one of the commits supporting UEFI (f5dd1af).
If you want to share code between nt and uefi, the nt version of ShvOsPrepareProcessor should return SHV_STATUS_SUCCESS in default flow :)
