We validated that commit 38816336a5 ("node_device_conf: Don't leak
@physical_function in virNodeDeviceGetPCISRIOVCaps") [0] indeed fixes
the leak investigated. Although there are more definitely-lost memory
reports from Valgrind, they are ultimately glibc-related and given the
report was in Trusty and they are not considerable leaks (at most,
8K/24H) our focus will be to fix the PCI-related leak in all libvirt
releases.

SRU template and debdiffs will get added here soon.
Cheers,


Guilherme

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.
