you can do that by sudo gedit /lib/udev/rules.d/les and pasting the line then saving.add line KERNEL='kvm', GROUP='kvm', MODE='0666' to les.configure -enable-sdl -enable-opengl -enable-virglrenderer -enable-system -enable-modules -audio-drv-list=pa -target-list=x86_64-softmmu -enable-kvm -enable-gtk Download latest qemu sources using git clone.cd into directory you want to download and build qemu(if you use arch linux you don't have to build qemu.just use the package in official repository.also it is not necessary to add your user to kvm just works.).Install the following build dependencies(no need to build for arch linux read below) using sudo apt install -y build-essential libepoxy-dev libdrm-dev libgbm-dev libx11-dev libvirglrenderer-dev libpulse-dev libsdl2-dev libgtk-3-dev libsdl1.2-dev ninja-build.
