[ovirt-users] build OVA file from ovf file + files with RAW disks

Hi, for backup VM i use script to create snapshot and then attach disks of VM to backupVM where i do copy of this disk . Also i backup OVF file. for restore , i just upload disk to corupted VM and attach. But ,, if i want to make some easy restore GUI,, it will be easier if i build OVA file from restored OVF and raw disks and then through API just import VM from OVA. The problem is i cannot find any correct way to to build correct OVA file for OVIRT. is there some playbook or script or way ho to do ? thank you Jan
