BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3902 TdIsEnabled() uses the CPUID instruction. At this point, exception handling is not established and a CPUID instruction will generate a #VC and cause the booting guest to crash. CcProbe() checks Ovmf work area to return the guest type. So call of CcProbe() instead of TdIsEnabled() to fix the above issue.
