Mac OS X에서 CPU 가상화를 위한 Intel VT-x support 지원여부 확인

How to check that Intel VT-x is supported in CPU:

# sysctl -a | grep machdep.cpu.features

3. You may see output similar to the one bellow

Mac:~ user$ sysctl -a | grep machdep.cpu.features
kern.exec: unknown type returned
machdep.cpu.features: FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV PAT CLFSH DS ACPI MMX FXSR SSE SSE2 SS HTT TM SSE3 MON VMX EST TM2 TPR PDCM

If you see VMX entry then CPU supports Intel VT-x feature, but it still may be disabled.

Please install all firmware updates from Apple to resolve this issue
