Nova-Neutron live-migration - ACTIVE/INACTIVE port bindings issue * nova needs vif plug event for inactive bindings * live migration with ml2-ovs only works by luck * agentless drivers does not support this https://bugs.launchpad.net/neutron/+bug/1834045 https://bugs.launchpad.net/neutron/+bug/1840147

Agreements: * document the nova-neutron live migration workflow to create a common base for discussion. Add ijw and sean-k-mooney to the review

SR-IOV live migration utilizing kernel NET_FAILOVER feature * aim to support live migration with SRIOV nic without traffic interrupt by bonding a virtio interface to the SRIOV nic in the guest kernel with NET_FAILOVER. * https://www.kernel.org/doc/html/latest/networking/net_failover.html * There was multiple solution proposlas but no agreements about which one to pursue. * TODO: adrianc to propose a nova spec based on the discussion

Correlation of Bandwidth RP with PCI RP when PCI will be tracked in Placement * Early heads up to Neutron team that Nova things about modelling PCI in Placement * Current best thinking on Nova side is to correlate BW RP with PCI RP in placement with a placement aggregate. * Nova will do the correlation * Neutron needs to prepare for possible BW RP generation conflict * Agreement: Neutron is OK with this plan. rubasov can help with the neutron impact when nova makes progress.
