Explore three key Nova features from the Epoxy and Flamingo cycles in this 29-minute conference talk that addresses hardware management challenges for OpenStack operators. Learn about support for VFIO variant drivers, which enables Nova to handle SR-IOV interfaces used by third-party drivers like GPUs, including passthrough and live migration capabilities. Discover how one-time-use (OTU) devices allow Nova to reserve devices after use, enabling operators to safely clean them before reuse and improve tenant isolation. Understand the placement over-capacity fix that resolves a long-standing bug preventing allocation changes in overcommitted environments, now allowing updates that improve or maintain capacity usage. Gain insights into better control, increased flexibility, and reduced surprises when managing PCI passthrough, GPUs, accelerators, and tightly managed resource pools in OpenStack environments.
