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. https://review.openstack.org/#/c/185973/
 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. https://review.openstack.org/#/c/190561/
 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
https://blueprints.launchpad.net/nova/+spec/add-nvme-bus-to-kvm-hypervisor
 vHost Support
https://blueprints.launchpad.net/cinder/+spec/vhost-support
Notes:
Some of the BPs would be resubmitted for Release M
Collaboration on SFV related works are highly welcomed.
