Topics for Discussion
Topic: Live Migration issues with DVR (Swami)
- We have started a discussion on the live migration issue with DVR and how to address it from the neutron side. As a team we need to
get consensus on this ideas before we work with the Nova team on this issue. I would like to discuss this today in our team meeting to get everyone on the same page.
