That means either there already is another libvirtd running or the
previous one died unexpectedly without removing this PID file. You can
distinguish these two via 'pgrep libvirtd' which either gives you the
very same PID as the one in the PID file (=libvirtd is running) or
nothing and than you should be safe to remove the file and start
libvirtd again. However, if libvirtd keeps failing to initialize, there
might be a misconfiguration problem (and libvirt bug as well since we
ought to remove PID file before quiting).
