 It's possible to run a single command before running testing suites using
 ``--run-command`` option as following:
 
 .. code-block:: bash
 
     kirk --run-command ./setup_sut.sh \
-           --sut qemu:image=folder/image.qcow
+           --com qemu:image=folder/image.qcow \
+           --sut default:com=qemu
