thanks Lubosz! I should explore further if floating IPs will help here. Can you also please clarify if VM IP is stored in the DB the IPs that have been assigned to a VM so there should be no risk of the dhcp giving it a new IP suddenly? That would cause a nightmare with real tenants soon coming onboard my deploy. I know there are some dnsmasq dhcp files in /var/lib/neutron/ on my Networking nodes, but what if I replace one of them with a fresh install, will the necessary vm details such as IP etc. be retrieved from the DB? thx will
