Package: python-nova
Version: 2014.1.3-6
Severity: grave
Tags: upstream
Justification: renders package unusable
Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
Running openstack on jessie. Starting or migrating VMs leads to errors like
libvirtError: operation failed: filter
'nova-instance-instance-00000012-fa163e8eb435' already exists with uuid
6b2b71c1-486c-4ef2-b0e3-1c0918bd317f
* What exactly did you do (or not do) that was effective (or
ineffective)?
Including patch from https://review.openstack.org/#/c/122721/
