   Importance: High => Critical

** Summary changed:

- Nova kilo requires concurrency 1.8.2 or better
+ [SRU] Nova kilo requires concurrency 1.8.2 or better

** Description changed:

- 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.
+ [Impact]
+ Some operations on instances will fail due to missing functions in oslo-concurrency 1.8.0 that the latest Nova stable release requires.
+ 
+ [Test Case]
+ Resize or migrate an instance on the latest stable kilo updates
+ 
+ [Regression Potential]
+ Minimal - this is recommended and tested upstream already.
+ 
+ [Original Bug Report]

  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.
