Hi Ed You might want to look into abusing the mechanisms we provide to record additional MAC and IP addresses for containers on a machine. The machine (Juju really) tells MAAS to associate a particular MAC and IP address with that machine in a way which will then be garbage collected if the machine is repurposed later.
I think the full fix must be to teach MAAS about Infiniband, which would mean: * the ephemeral image needs to have the necessary drivers to see it * we need to record it in the MAAS database as an infiniband device * we need to also record if you're going to do IPoverIB * the installation needs to set that up If you're up for this, we'll help steer the patches home. Otherwise, can put it on the list for 16.10.
