Upgrade from OSP10 to OSP11 Actual results: Upgrade fails. Expected results: Upgrade succeeds.
By the look of the review, it looks like - python-UcsSdk - python-networking-bigswitch - openstack-neutron-bigswitch-lldp - openstack-neutron-bigswitch-agent Sould be removed during the upgrade. Going to check, but the problem should be upstream as well.
We need a way to detect if bigswitch plugin is used to be able to conditionally delete it.
The issue upstream is not related to the package above ^ It's related to the python-networking-odl package. I'll fill a LP bug on it, maybe i'll try to submit a fix to the networking-old project
I add a fix in the bigswitch code: https://review.openstack.org/419422 The networking-odl is already fix but not in the dlrn repo, we need to get the latest release (from dec 8) 3.2. For now to workaround the issue we can add in the UpgradeInitCommand: yum remove -y python-UcsSdk openstack-neutron-bigswitch-agent python-networking-bigswitch openstack-neutron-bigswitch-lldp python-networking-odl
