[ovirt-users] Re: trying to use Managed Block Storage in 4.3.2 with Ceph / Authentication Keys
OK, /var/log/ovirt-engine/cinderlib/cinderlib.log says:

I don't really know what to do with that either.
BTW, the cinder version on engine host is "pike"
(openstack-cinder-11.2.0-1.el7.noarch)
Not sure if the version is related (I know
it's been tested with
pike), but you can try and install the latest rocky (that's what I use
for development)
Shall I pass "rbd_secret_uuid" in the driver options? But
where is this
UUID created? Where is the ceph secret key stored in oVirt?
I don't think
it's needed as ceph based volumes are no longer a
network disk like in the cinder integration, but it is attached like a
regular block device
The only things that are a must now are "rbd_keyring_conf" and
"rbd_ceph_conf" (you don't need the first if the path to the keyring
is configured in the latter)
And I think you get the error because it's missing or incorrect, since
I manually removed the keyring path from the configuration and got the
same error as you
