Hey there, I'm having problem in running virtual device, even if I've completed all the downloads in "EXTRAS"

This is the error :
Cannot launch AVD in emulator.
emulator: ERROR: x86 emulation currently requires hardware acceleration!
Please ensure Intel HAXM is properly installed and usable.
CPU acceleration status: HAX kernel module is not installed!

I'm learning Android App Development from ur Videos only. Please help me out for that. Thank You.
