Henry, can you please write a small note on how to trigger this error (w/o tempest) ? It'd be easier for triaging.

As a side note, please take a look this when filing bugs -- https://wiki.openstack.org/wiki/BugFilingRecommendations )

[Kashyap Chamarthy (kashyapc)]

Also,

  (1) Gerrit logs don't last forever, so it's not really ideal to point them when filing bugs.
  (2) Pasting IRC conversation without context isn't really much useful.

Thanks Flavio for pointing it out.

Please remember, these bugs are archived, and will be later referred.

Thanks.

These can be seen all over the compute logs of every recent tempest run.

Looks like something raises them for every instance being spawned. Mostly they appear to be cosmetic as tests succeed despite these errors.

    Stop libvirt errors from outputting to strerr

    When a libvirt error happens, the default is to output to stderr. This
    behavior can be omitted by registering a new error that simply passes
    without doing anything.

    Resolves bug 1182184.
