[Xen-devel] Xen and Infiniband as dom0 (only)

[Xavier Beaudouin <xb@xxxxxxxxxxx>]

Hello there,

I am trying to make infiniband working on a dom0.  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 ?

Thanks,
Xavier
