Help with XCP-ng VM Migration between two standalone hosts

I am unable to choose my bonded connection to migrate VMs between two standalone hosts. The hosts each have a local NVMe SR set up. I am using XO from the sources VM but I have also tried via XCP-ng Center but neither list the LAGG as available to use for the migrations. The link is fine and working as far as I can tell. I would appreciate any and all help.
