I'm using Ubuntu 14.04. I recently installed Android Studio, but whenever I try to run a Hello World app, I get this error:
/home/praveen/Android/Sdk/tools/emulator -avd Nexus_6_API_21 -netspeed full -netdelay none emulator: ERROR: x86 emulation currently requires hardware acceleration! Please ensure KVM is properly installed and usable. CPU acceleration status: KVM is not installed on this machine (/dev/kvm is missing).
