Description of problem:
rhos15 , cinder backend LVM.

Scenario :
create a signed image (barbican)
created an encrypted volume - empty
extend encrypted volume - passed
boot an instance from image ---> works.
Try to attach encrypted volume to the instance - > Fails.
Try to attach clear volume - works.

From compute logs , here is the traceback:

handling: libvirt.libvirtError: internal error: unable to execute QEMU command 'device_add': Property 'vi

Version-Release number of selected component (if applicable):

How reproducible:
Try to attach encrypted volume to instance.

Attaching logs from compute - logs directory and configuration files.

Thanks,

Please can I login to the environment to debug?

Hi ,
Yes you can access to :
root@titan50.lab.eng.tlv2.redhat.com
pass: 12345678

overcloud) [stack@undercloud-0 ~]$ nova list --all-tenants
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

(overcloud) [stack@undercloud-0 ~]$ cinder list --all-tenants
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------+

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------+

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
(overcloud) [stack@undercloud-0 ~]$

You can try:
nova volume-attach 62d454d1-1ca8-4e39-a778-92542d21dd9c d9285b64-31e1-404f-8f18-cdac6b4ffa4e

Note: Logged in and I can reproduce. However, I can't work out how to enable libvirt debug logging. Parking until I can get help to do this.

Here's the issue:

It looks like nova (via os-brick) is formatting the volume with LUKSv2, but qemu only supports LUKSv1. We need to fix os-brick to create LUKSv1.

— Additional comment from on 2019-06-10 11:58:31 UTC —

the os-bricks bug upstream is https://bugs.launchpad.net/os-brick/+bug/1831994
which has been fixed on master and the backport is pending https://review.opendev.org/#/c/663999/1

so once qemu supports luksv2 we can revert the default on master to use v2 if supported by qemu.

I'm going to repurpose this bug to track the top level openstack-nova feature, clone this to openstack-cinder, clone that to python-os-brick and finally write a fresh seperate RHEL RFE for native QEMU LUKS2 support.
