This for maintenance issues or priority issues on a HPC cluster for example. This case of container migration is problably the most interesting and the performance should be more than acceptable. May be not a top priority for the moment. thanks, C. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
