Thanks a lot for the response.

I am not sure if I asked it right: I already have Infiniband installed on
my kernel and it is working fine in the user space. However, I would like
to use the RDMA Verbs API inside the Xen code, like calling RDMA functions
to send/receive data. That requires Infiniband headers to be included in
the Xen code, but I'm have difficulty with that. So is there any sample
code of someone already calling Infiniband/RDMA functions within Xen code
or any guide on how to recompile Xen with custom headers?

Thanks a lot!
