It’s possible with the API, see http://ovirt.github.io/ovirt-engine-api-model/master/#services/disk/methods/... On Tuesday, October 11, 2022, Jonas <jonas@rabe.ch> wrote:

Hi there

I want to create incremental backups of a few imported VMs, but the VM disks are in the raw disk format which does not support incremental backup. Is there a way to convert existing disks from raw to qcow in oVirt? Since qemu-img can do this,I assume there must be a way..

Thank you Jonas
