Zide Chen 36ba7f8aa8 hv: clear CPUID.07H.EBX[2] to disable SGX from guests ... Regarding SGX, guests could access CPUID.07H.EBX[2] before query CPUID leaf 12H. Intel SDM 36.7.2: "If CPUID.(EAX=07H, ECX=0H):EBX.SGX = 1, the processor also supports querying CPUID with EAX=12H on Intel SGX resource capability and configuration." Clear CPUID.07H.ECX[30] SGX_LC to make the guest view consistent.
