I installed android studio 2.0 on my windows 7 ultimate, and I installed all the packages required by the android also the HAXM package is also installed. When I tried to run the emulator, it didn't run, a message popped up that said vt-x should be enabled in bios security settings, this is the pic.
I went in the bios settings but the Virtualization was already enabled over there, but when I installed a software called speccy to know about what all is included in my computer and I found in the cpu section showing that virtualization is supported but it is disabled.
Also when I ran the emulator it was written on top that /dev/kvm is not found I searched for it but it was related to linux distro I have provided some screenshots of that error this is the pic.
Go to BIOS setting of your PC after restart. Then enable virtualization in your BIOS configuration.
I had the same issue yesterday and I solved it by following the instructions here. I did the following:
- Uninstalled Intel x86 Emulator Accelerator (HAXM installer) 6.0.1 from Android Studio: use Tools->Android->SDK Manager->Appearance & Behavior->System Settings->Android SDK, select the tab SDK Tools, uncheck Intel x86 Emulator Accelerator and press Apply;
- Closed Android Studio;
- Uninstalled Intel Hardware Accelerated Execution Manager from Control Panel->Program and Features;
- Opened Android Studio and re-installed Intel x86 Emulator Accelerator from the same menu in Tools->Android->SDK Manager->Appearance & Behavior->System Settings->Android SDK.
Alternatively, one can use the Launch Standalone SDK Manager, open the Extras folder, check Intel x86 Emulator Accelerator and press Delete 1 package (or Install).
It seems that my installation of Intel Hardware Accelerated Execution Manager (HAXM) was corrupted. It is located under:
C:\Users\<name>\AppData\Local\Android\sdk\extras\intel\Hardware_Accelerated_Execution_Manager
