[Users] Host Non-Operational from sanlock and VM fails to migrate

I have a 2 node oVirt 3.3.2 cluster setup and am evaluating the setup for production use on our HPC system for managing our VM infrastructure. Currently I'm trying to utilize our DDR InfiniBand fabric for the storage domains in oVirt using NFS over RDMA. I've noticed some unstable behavior and it seems in every case to begin with sanlock. The ovirt web admin interface shows the following message as first sign of trouble on 2014-Feb-03 07:45. "Invalid status on Data Center Default. Setting Data Center status to Non Responsive (On host vm01.brazos.tamu.edu, Error: Network error during communication with the Host.).". The single VM I had running is stuck in the "Migrating From" state. virsh shows the VM paused on the crashed host and the one it attempted to migrate to. Right now I have a few concerns. 1) The cause of the sanlock (or other instability) and if it's related to a bug or an issue using NFSoRDMA. 2) Why the VM failed to migrate if the second host had no issues. If the first host is down should the VM be considered offline and booted on the second host after first is fenced? Attached are logs from the failed host (vm01) and the healthy host (vm02) as well as engine. The failed host's /var/log/message is also attached (vm01_message.log). Thanks - Trey
