[ovirt-users] Cannot export VM to another data domain. "o.original_template is undefined"

Hello, 4.4.10 Gluster based cluster w/ 3 nodes. I'm backing up all VMs before upgrading the setup to 4.5. (Hopefully done right before 4.5.1 w/ Gluster fix is released). When trying to export a VM to another data domain, several VMs show the following error: "Export VM Failed. o.original_template is undefined". Engine log looks clean (I see nothing about the failed upgrade). Any idea what's broken? - Gilboa
