Add support for logging to the systemd journal, using its simple client library. The benefit over syslog is that it accepts structured log data, so the journald can store individual items like code file/line/func separately from the string message. Tools which require structured log data can then query the journal to extract exactly what they desire without resorting to string parsing While systemd provides a simple client library for logging, it is more convenient for libvirt to directly write its own client code. This lets us build up the iovec's on the stack, avoiding the need to alloc memory when writing log messages. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
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.
