Description Konstantin Shalygin 2021-08-24 17:18:19 UTC 
Description of problem:

Managed Block Storage with Ceph backend is't support live disk migration between pools.

Version-Release number of selected component (if applicable): 4.4.8


Actual results:

oVirt Host use kernel rbd driver to mount disk. And admin can't use different method.

Expected results:

oVirt administrator optionally can use libvirt rbd driver. The userspace driver can be easy updated without downtime's and in librbd v14.2.2+ rbd migration feature is present.

Benny, any inputs on this?
Comment 3 Arik 2021-12-27 15:48:57 UTC 
It is unlikely that we will be able to implement this since it depends on enhancements on the cinderlib side
