Pull request overview
Adds support for a CPU topology “pinning profile” that requests CPU allocations from the EPA orchestrator by percentage, then splits the resulting allocation into Nova dedicated/shared CPU sets for nova.conf rendering.
Changes:
- Introduce
compute.cpu-pinning-profileconfig to drive percent-based CPU allocation and dedicated/shared splitting. - Add new socket protocol schema/action (
allocate_cores_percent) and client helper to request allocations by percentage. - Update unit test expectations and document the new config option in
README.md.
