    Stop libxl driver polluting logs on non-Xen hosts
    
    If the libxl driver is compiled in, then everytime libvirtd
    starts up on a non-Xen Dom0 host, it logs a error message.
    Since this is an expected condition, we should not log at
    'error' level, only 'info'.
    
    * src/libxl/libxl_driver.c: Lower log level for certain
      expected errors during driver init
