virFileReadAll already logs an error. If reading the 'speed' file fails with EINVAL, we log an error even though we ignore it. If it fails with other errors, we log two errors. Use virFileReadAllQuiet - ignore EINVAL and report just one error in other cases. Fixes this error on libvirtd startup: 2014-06-30 12:47:14.583+0000: 20971: error : virFileReadAll:1297 : Failed to read file '/sys/class/net/wlan0/speed': Invalid argument
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
