Sorry, this should have been all on one line but wrapped by my
mail client. Let's try again:

# python -c '\
        from ovirt_host_deploy import hardware; \
        v = hardware.Virtualization(); \
        print( \
                "OK" if \
                v.detect()==v.DETECT_RESULT_SUPPORTED \
                else "Not OK" \
        )'
