Stop the Storage domains in oVirt and attach the same Gluster volumes on the new cluster.Then Import the templates and the VMs from the new engine. Keep in mind that you might need to delete all VMs' snapshots and if needed to import the same VM as many times as the number of disks those VMs have. I would give a try to this one as theoretically might work:- revert the time on all hosts- block NTP- power on the engine. Then you can try to regenerate all certs and shutdown again to fix the time.

It gives me error 500 internal when I want to access. I have a new ovirt 4.5 on glusterfs which I would like to migrate all my vm's to. Is this possible? Can it be done by cli? It would save me from having to reinstall all the vm's._______________________________________________ Users mailing list -- users(a)ovirt.org To unsubscribe send an email to users-leave(a)ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/556KSQG5K6C...
