How to Check if Your CPU Supports Virtualization (VT-x / AMD-V)
Before running the VT Debugger, Hyper-V, WSL2 or Android emulators, confirm your CPU supports virtualization and it is enabled in BIOS. Here are the five most common detection methods on Windows.
Check Task Manager
Ctrl+Shift+Esc → Performance → CPU → look at 'Virtualization' at the bottom right: Enabled / Disabled / Not supported.
Tip: 'Virtualization: Disabled' means BIOS is off; a blank value usually means an old CPU without support.
systeminfo Command
Press Win+R, type cmd, run systeminfo and check the 'Hyper-V Requirements' section: Virtualization Enabled In Firmware: Yes/No.
Tip: If 'A hypervisor has been detected' appears, VBS/Hyper-V is already claiming virtualization.
Coreinfo Tool
Download Microsoft Sysinternals Coreinfo and run coreinfo -v; check if the VT-x (Intel) or AMD-V (AMD) line shows an asterisk.
Tip: An asterisk means supported & enabled; a hyphen means unsupported or disabled.
Check with CPU-Z
Open CPU-Z; under the CPU tab's Instructions section, look for VT-x (Intel) or SVM (AMD).
Tip: CPU-Z shows instruction support only, not whether BIOS has enabled it.
CPUID Command-Line Check
Use WMI: Get-CimInstance Win32_Processor | Select Name, VirtualizationFirmwareEnabled.
Tip: VirtualizationFirmwareEnabled=True plus SecondLevelAddressTranslationExtensions=True means fully ready.
What If It's Disabled
Reboot into BIOS: enable VT-x (Intel Virtualization Technology) on Intel, SVM Mode on AMD, save and re-check.
Tip: Some laptops require AC power to modify BIOS virtualization options.
