Your CPU does not support VT-x. Intel HAXM is required to run this AVD. Your CPU does not support VT-x.
Unfortunately, your computer does not support hardware accelerated virtualization. Here are some of your options: 1) Use a physical device for testing 2) Develop on a Windows/OSX computer with an Intel processor that supports VT-x and NX 3) Develop on a Linux computer that supports VT-x or SVM 4) Use an Android Virtual Device based on an ARM system image (This is 10x slower than hardware accelerated virtualization)
What do I do to get around this limitation?
回答1:
According to Android Documentation, to run an emulator the development system's CPU should support one of the following virtualization extensions technologies:
- Intel Virtualization Technology (VT, VT-x, vmx)
- AMD Virtualization (AMD-V, SVM) -- only supported for Linux
Your CPU is Intel Pentium B940, which according to the manufacturer does not support Intel Virtualization Technology (VT-x). That's the reason for this error.
The workaround is to use an alternative Android Emulator, e.g. Genymotion.

A solution from Android Studio documentation: If you have an AMD processor in your computer you need the following setup requirements to be in place:
- AMD Processor – Recommended: AMD® Ryzen™ processors
- Android Studio 3.2 Beta or higher – download via Android Studio Preview page
- Android Emulator v27.3.8+ – download via Android Studio SDK Manager x86 Android Virtual Device (AVD) – Create AVD
- Windows 10 with April 2018 Update
- Enable via Windows Features: “Windows Hypervisor Platform”.
Restart your system. For more visit: Android: Your CPU does not support VT-x
