Duplicate question missing therefore I vote to reopen. –  Matt Oct 11 '13 at 0:56
    
BTW, Infiniband support in the kernel for Centos 5.x which Xen Server is based on (not sure about XCP) is actually broken. It might be possible to get it working but some header files are broken in that particular release. –  Matt Oct 11 '13 at 0:57
    
I think you'll still need Ethernet, leave it enabled. If you do manage to get the drivers for the IB into the kernel working you'll also need to configure this by hand from the command line. –  Matt Oct 11 '13 at 0:59

The IB stuff has nothing to do with Ethernet, so steer clear of that. You don't mention what OS you're using, but the OFED includes IPoIB (which works on Windows, Linux, and FreeBSD).

This site has some really good walk-throughs to get you running. If you're still having issues after following those ask another question here. If the question relates to more "basic" network usage you might also consider Unix & Linux (who deal with hobby and home usage of Linux). –  Chris S Jul 18 '13 at 15:48
