From: dubobo <dubobo@xxxxxxxxxxxxxxx>
the libvirtd pid file is not match the os process pid number
which is smaller than before.
this would be exist if the libvirtd process coredump or the os
process was killed which the next pid number is smaller.
you can be also edit the pid file to write the longer number than
before,then restart the libvirtd service.
