BTW: would it be possible to export as ova on a path on host that is an
NFS share, bypassing export domain setup, or does it require local storage?

Strange: I tried from the GUI with a vm with 3 disks and specifying a

convert" where destination is on the storage domain itself???
Does it need this step before writing to the destination I chose? I hope
no...
