Hi,

I wanted to try ceph with oVirt and so I've installed an openstack
queens (current stable) environment containing cinder and keystone. But
when I tried to add the storage provider I ended up with 404 errors in
the engine log files.
They are because oVirt tries using the v2.0 API, and
http://HOST:5000/v2.0/tokens does not exist.
If I understand the release notes of openstack correctly the section
https://blueprints.launchpad.net/keystone/+spec/removed-as-of-queens
includes all v2.0 API being removed from keystone. So I'm asking whether
there is support for the v3 API in sight?

Daniel, do we have any support for v3?

Basically Ceph support via Cinder is not fully supported. Even if you get

the API to work, we don't support lot of operations like moving disks between

Ceph and other storage types. This should be improved in 4.3, but we don't

have concrete plans yet.

You can also try other ways to integrate Ceph, like cephfs or Ceph iSCSI gateway.

These options are fully supported as they use the existing file and block based

capabilities.
