Why would you want to see /sys/class/infiniband/? There things are only there for direct HW access, guests do not get that. You should be able to use SRP and IPoIB - you set it up in host (dom0) and guests use it as any other network/storage device through the virtualization layer. -- MST _______________________________________________ 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
