I have a Lenovo ThinkPad T540p with QM87 chipset (VT-d capable) and Haswell Dual-Core i5-4200M (VT-x only, no VT-d) running Windows 8.1 Pro 64-bit. The BIOS page shows Intel Virtualization Technology (means VT-x only) enabled. No VT-d mentioned anywhere. So this laptop has VT-x only without VT-d...
