title: kvm permission denied on Android Studio emulator
body: <p>When I try to run an AVD, I get this erros:</p>
  
  <pre><code>/dev/kvm device permission denied
  </code></pre>
  
  <p>Yeah, I know, I don't have the permission to access <code>/dev/kvm</code>, I know that I can "solve" it by changing the <code>/dev/kvm</code> permission to my user, and set my user to kvm group, it is working but when I restart my user session, the <code>/dev/kvm</code> permission return to root user and root group, and I need to set the permission to my group again and again...</p>
  
  <p>How to set this permission and prevent that when I reboot my computer my permission are not changed anymore?</p>
