I'm not sure about smartio or Xen-IB, but you could try assigning both HCA PCI devices to your domU and see if it works better (the HCA should appear in lspci as both a PCI bridge and an actual HCA device, and the driver expects to find both) - R. _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
