Emulator Android_Accelerated_x86_Oreo cannot be started With Visual Stuido

Issue

I am developing android app with Xamarin by using visual studio. I have checked the windows hyper version and intel X86 but when I try to run the emulator , its not running and showing following errors on console window visual studio.

'"C:\Program Files (x86)\Android\android-sdk\emulator\qemu\windows-x86_64\qemu-system-i386.exe"' -partition-size 512 -no-boot-anim -verbose -feature WindowsHypervisorPlatform -avd Android_Accelerated_x86_Oreo -prop monodroid.avdname=Android_Accelerated_x86_Oreo Emulator Android_Accelerated_x86_Oreo cannot be started. Runtime checks completed Build has been canceled.

I tried to run the emulator but it showing following error message.

Here is the full console message.

Solution

the error message gives a pretty explicit message about what is wrong and how to fix it

emulator: CPU Acceleration: DISABLED emulator: CPU Acceleration status: Android Emulator requires an Intel processor with VT-x and NX support. (VT-x is not supported) emulator: ERROR: x86 emulation currently requires hardware acceleration! CPU acceleration status: Android Emulator requires an Intel processor with VT-x and NX support.
