Host only infiniband/10Gb ethernet vmbr?

[minasmorgul]

Hello,

I want to connect some VMs with one VM (acting as NFS-Fileserver) with maximum bandwith. All VMs are running on the same Node.

i'd like to create a infiniband/10Gb vmbr interface that is not bridged to a physical interface to get a host-only infiniband/10Gb network.

Is that possible? If yes, How to do it (detailed please, i'm a newbe)?

Regards,
minas
