[ovirt-users] Re: Debugging ceph access

Hi, I found the reason for my timeout problems: It is the version of librbd1 (which is 0.94.5) in conjunction with my CEPH test-environment which is running the luminous release. When I install the librbd1 (and librados2) packages from the centos-ceph-luminous repository (version 12.2.5) I'm able to start and migrate VMs inbetween the hosts.
