[ovirt-users] Clone template on MBS not working

I created a test-setup with oVirt 4.5.2 from scratch, with hyperconverged Ceph installed, with following services in use: - iSCSI Gateway for Hosted Engine Disk - NFS for disk upload/import - RBD/MBS for template disks and VM disks My issue now is that I can download a VM from ovirt-image-repository and import that as template into the NFS domain. After that I go into the template and copy the boot disk onto the block storage. This is successfully copied, and I go ahead and remove the original disk to the NFS storage domain. So now there is only one disk left on the Managed Block Storage domain. Cloning the template results in a failed attempt with erors in DeleteImageGroupVDS. Attached are vdsm.log, supervdsm.log and engine.log. On a related note: Copying the disk from NFS to MBS, then creating a VM, assigning that disk, making a template off of that and cloning that works just fine - though I then have following disks in RBD, which I'd like to avoid: - initial-disk imported to MBS for VM template [deleted] - template disk as snapshot of initial-disk - template clone disk as snapshot of template disk With the copying from NFS approach I get a template which is also the root disk, not a snapshot of a deleted disk. Is this something that hasn't been seen yet? Best, Jöran
