  qemu (1:2.5+dfsg-5ubuntu10.37) xenial; urgency=medium

  * d/p/lp1823458/add-VirtIONet-vhost_stopped-flag-to-prevent-multiple.patch,
    d/p/lp1823458/do-not-call-vhost_net_cleanup-on-running-net-from-ch.patch:
    - Prevent crash due to race condition on shutdown;
      this is fixed differently upstream (starting in Bionic), but
      the change is too large to backport into Xenial. These two very
      small patches work around the problem in an unintrusive way.
