You and Richard seem to have good experience of infiniband in 
virtualized environments. 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.
Thank you.
