Proxmox VE 3.2 Openvz container Migrate to NFS Storage

Hey all,
I have a fresh 4 node cluster (NO HA) with shared NFS storage. When I try and migrate a openvz container (running on the nfs storage) to another node it moves it to the local storage (small sad). How can I migrate a openvz container and leave it on the NFS storage?

Thanks,
Matt
