dev/kvm not found in android studio

I was facing 'dev/kvm not found' this issue. I was not able to launch emulator in android studio.

The I checked kvm in my system with below command:

$kvm-ok
sachin@sachin-E470:~$ kvm-ok
The program 'kvm-ok' is currently not installed. You can install it by typing:
sudo apt install cpu-checker

Then I ran below command:

sachin@sachin-E470:~$ sudo apt-get install qemu-kvm libvirt-bin ubuntu-vm-builder bridge-utils

Then I got :

sachin@sachin-E470:~$ sudo kvm-ok

INFO: /dev/kvm does not exist

HINT:   sudo modprobe kvm_intel

INFO: Your CPU supports KVM extensions

INFO: KVM (vmx) is disabled by your BIOS

HINT: Enter your BIOS setup and enable Virtualization Technology (VT),

      and then hard poweroff/poweron your system

KVM acceleration can NOT be used

Then I did:

sachin@sachin-E470:~$ sudo adduser sachin kvm  --where sachin is my username of on computer

Then I restarted system-->wen tto Bios-->security-->virtualization
and enabled both options for intel virtualization.

then started computer.

KVM issue solved.

Happy learning!!!
