To allow me fast = access to storage, and fast migration between hypervisor. I still don't want to do Ib as Hypervisor Accelerator and specialy what = is shown on slide 12 of this paper : = http://xen.org/files/Xen_Virtualization_InfiniBand_Mellanox_MKagan.pdf, = but I need rdma to get fast access to storage : - iSer (eg iscsi over infiniband) - RDMA for NFS over RDMA or stuff like this. On my host, without Xen (F12, with myoung kernel backported, xen = 4.0.0-rc6 and OFED 1.5.1-RC4), I can use correctly ipoib (IP over IB), = but rdma is still broken. Is there any people that has made dom0 IB working that can me some hints = about what I have to fix ?
