A change was made to make that fail fast and obvious now rather than let users think they had encrypted rbd volumes. The KeyError in nova should have a better exception raised with this change [2]. nagyz is working on adding the encryption support for rbd to nova here [3].

Re: [openstack-dev] [Cinder] encryption is not supported in ceph volume
Indeed, it works only for iSCSI Cinder backends. I believe there are at least two ways in which volume encryption for Ceph could be achieved: - by implementing encryption at librbd level (user space) - rewriting Ceph's Cinder plugin, to attach RBD images not through libvirt/librbd but for accessing Ceph use native Linux kernel RBD driver and stack LUKS atop of RBD (device-mapper way) Regards, Adam On Thu, Jul 30, 2015 at 8:02 AM, Li, Xiaoyan xiaoyan...@intel.com wrote: Hi all, I created an encryption type, and create a volume in Ceph with the volume type. cinder encryption-type-create But failed to attach it to a VM.
