[ovirt-users] Re: Long shot on VM failing to start
WARNING: The restore from 4.3 to 4.4 works only if it was taken from 4.3.10 Update before taking the backup ! Best Regards,Strahil Nikolov Thanks Tomas, The method choice was decided based on a few factors. 1. The environment is a Production Live environment which, through neglect, has been over utilised. 2. The stability of the cluster has been an issue which has resulted in several new clusters being built. 3. Zero or near to Zero downtime is a priority. 4. Lack of confidence in oVirt from certain quarters. Further investigation revealed a systemd-machined.service failure on all 3 nodes in the cluster. The service will not start without a reboot, which is a non runner at this time. A decision has been made to export and import the VMs to the new environments to avoid possibly extended outage periods.

Could you check journal for libvirtd if there are any errors? Also please check journal for vdsm and make sure the service did not restart.
