I was getting this error about VT-X/AMD-V Hardware Acceleration not being available on my system and was very confused because I had enabled it in the BIOS and still got the error. Today I decided to do a little research on it. I had remembered in the past reading about Hyper-V causing issues with other virtualization software. So I did some checking on my system, because I know that Hyper-V is enabled/installed when you install the Android Emulator with Visual Studio. I checked if the Hyper-V feature was enabled, and sure enough, it was. I disabled Hyper-V and rebooted my system. Fired up VirualBox and loaded up the VM. Success.
To disable Hyper-V
- Go to Control Panel –> Programs and Features
- Click Turn Windows features on or off
- Uncheck Hyper-V
- Click OK
