Hello Nova core team, I have three small patches implementing ephemeral storage encryption for LVM backed instances. https://review.openstack.org/#/c/40467/ https://review.openstack.org/#/c/60621/ https://review.openstack.org/#/c/61544/ The patches have been under review for a couple months now and have gone through several rounds of revisions. There are already a number of +1's and the patches are only awaiting +2's, and in one case a +1, from the core team. Thank you for your help, Dan
