Hey folks,
thank you all for your replies. Turns out that in my use case creating a
gluster volume manually, moving the DC folder back into gluster and
importing the domain in oVirt Engine did the trick.
The followed importing of the VMs was a bliss and really worked
streamlined. I am truly baffled and amazed.
I found my backup & disaster recovery option.
Thank you all again for replying!
