[ovirt-users] export VM from oVirt engine 3.5

Hello, I am trying to export a bunch o VM from oVirt version 3.5 The problem is that there is no OVA support for exporting them. I also tryed to export VMs into OVA format using ovirtsdk4 which anyway won't work on oVirt 3.5. I can successfully export to a NFS partition but for each VM there are several qcow v2 files which I suppose to be the VM image and its snapshots. How to identify the correct file to represent the current VM status ? If I delete all the snapshots, will I end up with only one valid qcow v2 image that I can use ?
