KVM is required to run this AVD. /dev/kvm device: permission denied. code example

Example 1: grant current user access to /dev/kvm

first install dependecies of kvm from android studio site then execute following command

Add your user to kvm group using:
sudo adduser $USER kvm

If still showing permission denied:
sudo chown $USER /dev/kvm

Example 2: where is /dev/kvm

This is how I got it to work in Ubuntu 18.04

1. Install qemu-kvm
$sudo apt install qemu-kvm

2. Add your user to kvm group using:
$sudo adduser <Replace with username> kvm


3.If still showing permission denied:
$ sudo chown <Replace with username> /dev/kvm

This works!

Example 3: dev/kdm device permission error android studio

$ grep kvm /etc/group
  kvm:x:131:
$ sudo adduser $USER kvm
