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.
Regards
Bernhard

Hi,
as you might already know I try to use ceph with openstack in an oVirt
test environment. I'm able to create and remove volumes. But if I try to
run a VM which contains a ceph volume it is in the "Wait for launch"
state for a very long time. Then it gets into "down" state again. The
qemu log states

2018-05-25 15:03:41.109+0000: shutting down, reason=failed
On the monitor hosts I see traffic with the ceph-mon-port, but not on
other ports (the osds for example). In the ceph logs however I don't
really see what happens.
Do you have some tips how to debug this problem?
Regards
Bernhard
