Laine Stump 4cf974b674 network: restart radvd/dnsmasq if needed when libvirtd is restarted 
A user on IRC had accidentally killed all of his libvirt-started
dnsmasq instances (due to a buggy dnsmasq service script in Fedora
16), and had hoped that libvirtd would notice this on restart and
reload all the dnsmasq daemons (as it does with iptables
rules). Unfortunately this was not the case - as long as the network
object had a pid registered for dnsmasq and/or radvd, it assumed that
the processes were running.

This patch takes advantage of the new utility functions in
bridge_driver.c to do a "refresh" of all radvd and dnsmasq processes
started by libvirt each time libvirtd is restarted - this function
attempts to do a SIGHUP of each existing process, and if that fails,
it restarts the process, rebuilding all the associated config files
and commandline parameters in the process. This normally has no
effect, but will be useful in solving the occasional "odd situation"
without needing to take the drastic step of destroying/re-starting the
network.

         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.
