Hi Mike, Jay, and Walter, Please revisit this patch https://review.openstack.org/#/c/151959/ and don't revert this, thank you very much! I think it's apposite to merge the SDSHypervisor driver in cinder first, and next to request nova to add a new libvirt volume driver. Meanwhile nova side always ask whether the driver is merged into Cinder, please see my comments in nova spec https://review.openstack.org/#/c/130919/, thank you very much!
