But maybe a different one to the original author of this bu= g. At any rate, better logging in the jail system would be very welcome. --=20 You are receiving this mail because: You are the assignee for the bug.= From owner-freebsd-jail@freebsd.org Thu Jun 30 22:33:17 2016 Return-Path: <owner-freebsd-jail@freebsd.org> Delivered-To: freebsd-jail@mailman.ysv.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:1900:2254:206a::19:1]) by mailman.ysv.freebsd.org (Postfix) with ESMTP id DAD60B87CAA; Thu, 30 Jun 2016 22:33:17 +0000 (UTC) (envelope-from bz@FreeBSD.org) Received: from mx1.sbone.de (mx1.sbone.de [IPv6:2a01:4f8:130:3ffc::401:25]) (using TLSv1 with cipher DHE-RSA-CAMELLIA256-SHA (256/256 bits)) (Client CN "mx1.sbone.de", Issuer "SBone.DE" (not verified)) by mx1.freebsd.org (Postfix) with ESMTPS id A106A2738; Thu, 30 Jun 2016 22:33:17 +0000 (UTC) (envelope-from bz@FreeBSD.org) Received: from mail.sbone.de (mail.sbone.de [IPv6:fde9:577b:c1a9:31::2013:587]) (using TLSv1 with cipher ADH-CAMELLIA256-SHA (256/256 bits)) (No client certificate requested) by mx1.sbone.de (Postfix) with ESMTPS id B234125D3A9F; Thu, 30 Jun 2016 22:33:13 +0000 (UTC) Received: from content-filter.sbone.de (content-filter.sbone.de [IPv6:fde9:577b:c1a9:31::2013:2742]) (using TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits)) (No client certificate requested) by mail.sbone.de (Postfix) with ESMTPS id B3AB7D1F892; Thu, 30 Jun 2016 22:33:12 +0000 (UTC) X-Virus-Scanned: amavisd-new at sbone.de Received: from mail.sbone.de ([IPv6:fde9:577b:c1a9:31::2013:587]) by content-filter.sbone.de (content-filter.sbone.de [fde9:577b:c1a9:31::2013:2742]) (amavisd-new, port 10024) with ESMTP id Z-9S9yVqyJk4; Thu, 30 Jun 2016 22:33:10 +0000 (UTC) Received: from nv.sbone.de (nv.sbone.de [IPv6:fde9:577b:c1a9:31::2013:138]) (using TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits)) (No client certificate requested) by mail.sbone.de (Postfix) with ESMTPSA id BA463C7BC72; Thu, 30 Jun 2016 22:33:10 +0000 (UTC) Date: Thu, 30 Jun 2016 22:33:09 +0000 (UTC) From: "Bjoern A.

In addition some missing parts were virtualised or the virtualisation was fixed, e.g., pf and ipfilter, ipfw log interface. I have done some testing and stress testing but it's impossible to catch all combinations and setups or even options. So once 11.0-ALPHA6 is out please do test (or if you want to do so now r302302 or later). These changes are only and will only be in FreeBSD 11 for the time being. You will still need to compile your own kernel; GENERIC will not have VIMAGE enabled for 11.0 as that requires at least a performance analysis (due to extra layer of indirection). It will also still print the "experimental" feature line, as we do not want to commit to KPI/KBI or other things yet and we feel more testing would be good. I would advise to start testing on dedicated test-systems and not necessarily production servers but obviously that is your choice. Also if you are using ports that bring their own ifnet interfaces and you are experiencing problems please let us know. If you find problems please file a bug report and make sure to set "vimage" in the Keywords field but feel also free to post to freebsd-virtualisation@ which I'll be monitoring. Thanks a lot to everyone! Bjoern -- Bjoern A. Zeeb r15:7
