[ovirt-users] Re: oVirt 4.3 and cinderlib integration (for ceph) on CentOS 7 - centos-release-openstack-pike
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 On Mon, Jun 8, 2020 at 9:40 PM Mathias Schwenke wrote: > > > It looks like a configuration issue, you can use plain `rbd` to check > > connectivity. > Yes, it was a configuration error.

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 [1] https://bugzilla.redhat.com/show_bug.cgi?id=1755801 On Thu, Jun 4, 2020 at 11:49 PM Mathias Schwenke wrote: > > Thanks vor your replay. > Yes, I have some issues.

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 On Thu, Jun 4, 2020 at 10:00 PM Mathias Schwenke wrote: > > At > https://www.ovirt.org/develop/release-management/features/storage/cinderlib-integration.html > 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).
