Has anyone here been able to make Openstack + KVM work with Infiniband & 
NFS-RDMA?

I have spent a couple of days here trying to make it work, but with no 
luck.  At first I thought the problem was NFS3 and lockd, but I tried 
NFSv4 and I have the same problem.  I also disabled AppArmor just as a 
test but that didn't help.

Things work fine with Infinband if I don't use RDMA, and I have many 
non-libvirt QEMU-KVM vm's working fine using RDMA.

When this problem occurs, the qemu process is CPU locked, strace shows 
calls to FUTEX, select, and lots of EAGAIN messages.  If nobody else here 
is using this setup, I'll keep digging to find out exactly which option is 
causing this problem.

Thanks,
Mark
