Thank you, I am trying to migrate a vm that has its disks on cephfs ( as posix domain - mounted on all hosts ),  and it does not work. Not sure if this is normal,  considering the vm disks being on this type of storage.  The error logs in engine are: 2019-03-02 13:35:03,483Z ERROR [org.ovirt.engine.core.vdsbroker.monitoring.VmAnalyzer] (ForkJoinPool-1-worker-0) [] Migration of VM 'centos7-test' to host 'node1.internal' failed: VM destroyed during the startup. 2019-03-02 13:35:03,505Z ERROR [org.ovirt.engine.core.vdsbroker.monitoring.VmsMonitoring] (ForkJoinPool-1-worker-14) [] Rerun VM 'bec1cd40-9d62-4f6d-a9df-d97a79584441'.

Any thoughts ?
