    If we see LINE_NOT_FOUND, the kvm group may need to be created along with permissions:

    If we see kvm:... but no username at the end, running the following command may allow KVM access:
        sudo gpasswd -a $USER kvm

    You may need to log out and back in for changes to take effect.

    $ ls -l /dev/kvm
    crw------- 1 root root 10, 232 Jul  5 13:27 /dev/kvm
    This should ideally be:
    crw-rw---- 1 root kvm 10, 232 Jul  5 13:27 /dev/kvm

    Manually changing it helps boot up the emulator. However, the settings are reverted on restart.

    $ sudo chgrp kvm /dev/kvm
    $ sudo chmod g+rw /dev/kvm
