Thanks for the input - I may not have explained myself properly though - I'm not considering pci-passthrough.
What I would like to confirm is, if there's any problems running storage traffic over OVS, latency/performance wise - in this case using SR-IOV VFs inside dom0, to seperate the traffic. What I think I need is two seperate networks on a XEN host - one for Openvswitch and one for NFS storage traffic. The problem here is that I then need to create 2xLACP bonds on the network cards - which may not be possible. The easy way would be to have just one LACP bond, connect OVS to it, and create a OVS interface for the storage and others for the VMs - but I'm having doubts if it will impact performance. Do you guys run NFS / iSCSI / AOE traffic over OVS or on seperate interfaces (physical or with SR-IOV(Intel) or nPAR (Broadcom)?
