Changes between Version 3 and Version 4 of Ticket #12458, comment 10

v3	v4
1		Part of the problem is with !VirtualBox... or Intel. The problem is there is no way to tell if the CPU is in SMX mode or not. If anyone finds a legal, reliable way to do this, do let me know ;)

3	3	!VirtualBox 4.3, over ambitiously treats CR4.SMXE bit to mean the CPU is in SMX mode, which strictly speak is not correct. That bit only indicates that SMX mode can be used but not whether the CPU is in SMX mode or not. Normally, this bit should not be set unless the OS runs in trusted boot SMX mode.
