Hi Everyone, I attended the ops mid cycle summit on Tuesday and Wednesday and here are brief notes on the feedback I heard related to nova. Please feel free to add your comments or correct me if I got anything wrong.
Large Deployments Session [1]: - There's a Neutron spec [2] for adding the capability to model an L3 network which is composed of L2 networks that are routed together, and this project will require cooperation from the nova side - Cells v2 not coming along as quickly as expected. Cells v1 issues around compat between versions, understood it's not supported but it's been a problem - Hierarchical multi-tenancy isn't yet supported (quotas) Upgrades Session Report: - Good linking of features to documentation is important - Inter-service changes are important to call out - Flavor migration is an example of something done well Other general notes: - Event capture is a choice between two bad options - Information divided between events and logs. Have to capture both or you lose the whole picture - Hard to trace RPC calls - Race conditions with scheduling and quotas - The state of Nova and NUMA is not understood - Glance v2 is not being used. From what I understand, we can't move to it because images created by v1 can't be read by v2, for example? All of the etherpads from the event are linked here: https://etherpad.openstack.org/p/PAO-ops-meetup Thanks, -melanie (irc: melwitt) [1] https://etherpad.openstack.org/p/PAO-ops-large-deployments [2] https://review.openstack.org/#/c/196812/
