title: Infiniband + KVM
body: <p>despite quite a long search for days, I could not find any good information about the following - though I think, I can not be the first to have this problem: We are working on a high-performance-cluster with MATLAB, MPI and Infiniband. This setting has been working quite well over the last years. But to reach more flexibility and easier maintaining we are thinking about virtualizing the calculation nodes with KVM.</p>
  
  <p>Now I have the big problem of getting Infiniband "into" my virtual machine. I do not only want to passthrough the PCI-Interface but build something corresponding to a ethernet bridge which I can virtually connect to my machine(s) on my host. I found some sources that talk about this - but not how to install/configure IB. Does anyone out there have an idea how to this? </p>
  
  <p>Thanks in advance!</p>
