v5 v6 5 5 We might relax our checks a bit but the problem really is that Intel doesn't provide software with the necessary information to do proper sanity checking and error reporting in this area. 6 6 7 In fact, VMXON will #GP fault if invoked with the wrong combination of bits, so unless something fails earlier, !VirtualBox might crash your host kernel if the CPU is really in SMX mode but the BIOS through the MSR preventsVT-x in SMX mode.7 In fact, VMXON will #GP fault if invoked with the wrong combination of bits, so unless something fails earlier, !VirtualBox might crash your host kernel if the CPU is really in SMX mode but the BIOS (through the feature MSR) prevents using VT-x in SMX mode.
