Bug description:
  It was reported that libvirt 1.3.1 running on Trusty (through
  UCA/Mitaka) is getting OOM'ed after a while - in our reports took 2
  years for the leak to trigger an out-of-memory situation, but this may
  change according to the user available memory.

  Valgrind was executed in a similar environment, we were able to
  collect information about the "definitely lost" memory of libvirt
  process (attached) below.

  The leaks are detailed in next comments.
