This issue was brought up about a year and a half ago. So I''ll bring it up again and see if anything happens. I''ve got an infiniband network and am attempting to pass the infiniband card through the host and give it to the guest. I''m working with standard CentOS 5.2 on both guest and host with their provided xen (3.0.3 ish). I''ve also attempted to install the

Hi have what might be some elementary questions. Really, what I"d love would be for someone who has had good success to publish his/her configuration files and, maybe, the output from ifconfig. At this point, when I see the not-so-good performance I"m getting, I don't realistically know if I'm in the right ballfield. It seems to me, that with so many mellanox cards out

Data center backends use more and more RDMA or RoCE devices and more and more software runs in virtualized environment. There is a need for a standard to enable RDMA/RoCE on Virtual Machines. Virtio is the optimal solution since is the de-facto para-virtualizaton technology and also because the Virtio specification allows Hardware Vendors to support Virtio protocol natively in order to achieve
