Summary

Cross-HV resize supports only FCD-backed Cinder volumes at this time.

This change uses the newly introduced [cross_hv] fcd_volume_type to validate all attached Cinder volumes during cross-HV resize. Nova now rejects the resize if any attached volume does not use the configured FCD volume type. This covers:

  • BFV instances
  • Image-backed instances with attached Cinder volumes

Same-HV resize behavior does not change.
