Min M Xu	eff44c008d	OvmfPkg/VmgExitLig: HALT on #VE when access to private memory ... BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4125 EPT-violation #VE should be always on shared memory, which means the shared bit of the GuestPA should be set. But in current #VE Handler it is not checked. When it occurs, stop TD immediately and log out the error.
