The Xen-IB I said means VMM-bypass I/O virtualization of InfiniBand on Xen.
At the beginning, the link:
http://xenbits.xensource.com/ext/xen-smartio.hg I found is for that.
However, it looks like Xen-IB(as I said in first line) doesn't exist and no one would know how to build up it, right?

What is Xen-IB exactly?

That's right, there is no documentation and anyone who would have been
involved with this stuff is long gone.
