[Bug 1518016] Re: Nova kilo requires concurrency 1.8.2 or better

[Markus Zoeller (markus_z)]

The upstream stable/kilo branch contains the updated requirement: https://git.openstack.org/cgit/openstack/nova/tree/requirements.txt?h=stable/kilo#n31
Is this maybe not yet available in the Ubuntu OpenStack Nova Kilo release?

Title:
  Nova kilo requires concurrency 1.8.2 or better

Status in OpenStack Compute (nova):
  Incomplete
Status in python-oslo.concurrency package in Ubuntu:
  New

Bug description:
  OpenStack Nova Kilo release requires 1.8.2 or higher, this is due to
  the addition of on_execute and on_completion to the execute(..)
  function.  The latest Ubuntu OpenStack Kilo packages currently have
  code that depend on this new updated release.  This results in a crash
  in some operations like resizes or migrations.

  This commit above shows that OpenStack now requires 1.8.2 instead of
  1.8.0.  We would appreciate if the 1.8.2 upstream release can be
  brought in to resolve this bug.

  Thank you.
