  7. 7. OpenStack SFV related BPs  Improve nova attach volume api to support disk-bus : The purpose of this spec is to add disk-bus parameter to nova attach volume api.  Add local-to-instance to create server api : The purpose of this spec is to add "local_to_instance" to block_device_mapping parameter in nova create instance API.  Add volume type to create server API : Currently in create server API, using block_device_mapping parameter can create cinder volume and attach to instance, but there aren't volume type parameter to create a SLA based volume, so this bp will add the volume type to create api.  Add NVME bus to KVM hypervisor  vHost Support Notes: Some of the BPs would be resubmitted for Release M Collaboration on SFV related works are highly welcomed.
