Fails to create ova image

Engine creates a copy of the image in storage domain . As a process of creating ova, it fails to open the disk image which get created in storage doamin due to  permission issue. The image created by vdsm user. But the ansible playbook which opens the image uses root user.

Storage : NFS
Note: Export to Domain works fine
