Mohammed Naser (mnaser) wrote : Nova kilo requires concurrency 1.8.2 or better

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.
