Comment 2 for bug 1868221

Adding an exec field would not be right, because QEMU can't simply be launched from the desktop without any arguments. There needs to be a long string of arguments given that are different for every QEMU that is launched. The only viable way to actually launch QEMU is interactively from the terminal, or indirectly via a 3rd party app like virt-manager. We only created the qemu.desktop file in the first place because Wayland needs this to be present in order to identify what Icon to display for a window.
