I spent some time getting IB to work with XCP a few months ago. There should  be some info about this on this list.

I did not try to make it work for shared storage, but for inter-host communication. I ended up "manually" routing the XCP traffic over IPoIB.

My understanding is that there is no official IB support, but that Novell is working on something. I've also seen interest in using Lustre over IB as shared storage, but I don't think it's possible.

I do believe you can use IPoIB to access your NFS server, but I've not tried it myself.

I am running XCP 0.5.  I have an InfiniBand network in place that I would
like to use to connect to my NFS server for VM image storage.  Has anybody
tried getting IB to work with XCP?  Is there a document that outlines the
steps for getting IB to work with XCP?

Also, I don't need to expose the IB network to any of the domU.  I only want
to use the IB network to connecting to NFS based image storage.
