Extending Network Quality of Service support in OpenStack
summary
OpenStack adds a minimum guaranteed packet rate QoS implemented through Neutron, Nova and Placement so VMs are scheduled only to hosts that report enough packet-processing capacity; bandwidth already has both scheduling and data‑plane throttling. Demo on a DevStack single-node uses an OVS bridge configured for 5 Mbps per direction and 100 pps, showing Placement resource providers (bridge and packet-processing) and live allocations. The work spans ~40k lines of code across >200 commits; CLI and HOT template bits still await review.
