May I ask one thing? We were thinking about buying some Mellanox Connectx-2 for use with SR-IOV (hardware virtualization for PCI bypass, supposedly supported by connectx-2) in KVM (also supposedly supports SR-IOV and PCI bypass). Do you have info if this will work, in KVM or other hypervisors? I asked in KVM mailing list but they have not tried this card (which is the only SR-IOV card among Infiniband ones, so they have not tried infiniband). We can be interested in both true infiniband and IPoIB support.
