ist described the cinderlib integration into oVirt:
Installation:
- install centos-release-openstack-pike on engine and all hosts
- install openstack-cinder and python-pip on engine
- pip install cinderlib on engine
- install python2-os-brick on all hosts
- install ceph-common on engine and on all hosts
Which software versions do you use on CentOS 7 whith oVirt 4.3.10?
The package centos-release-openstack-pike, as described at the above-mentioned Managed
Block Storage feature page, doesn't exist anymore in the CentOS repositories, so I
have to switch to centos-release-openstack-queens or newer (rocky, stein, train). So I get
(for using with ceph luminous 12):
- openstack-cinder 12.0.10
- cinderlib 1.0.1
- ceph-common 12.2.11
- python2-os-brick 2.3.9

New subject: oVirt 4.3 and cinderlib integration (for ceph) on CentOS 7 - centos-release-openstack-pike
I've used successfully rocky with 4.3 in the past, the main caveat
with 4.3 currently is that cinderlib has to be forced to be 0.9.0 (pip
install cinderlib==0.9.0).
Let me know if you have any issues.
Hopefully during 4.4 we will have the repositories with the RPMs and
installation will be much easier

Thanks vor your replay.
Yes, I have some issues. In some cases starting or migrating a virtual machine failed.
At the moment it seems that I have a misconfiguration of my ceph connection:

yes, it looks like a configuration issue, you can use plain `rbd` to
check connectivity.
regarding starting vms and live migration, are there bug reports for these?
there is an issue we're aware of with live migration[1], it can be
worked around by blacklisting rbd devices in the multipath.conf

connectivity.
Yes, it was a configuration error. I fixed it.
Also, I had to adapt different rbd feature sets between ovirt nodes and ceph images. Now
it seems to work.

yes, that's because cinderlib uses KRBD, so it has less features, I
should add this to the documentation.
I was told cinderlib has plans to add support for rbd-nbd, this would
eventually allow use of newer features
