[Pkg-xen-devel] Bug#554805: xen-utils-3.2-1: ioemu routed networking on HVM guests fails
Package: xen-utils-3.2-1 Version: 3.2.1-2 Severity: normal Under this Xen setup, (Linux) HVM guests fail to have network active when running with *routed* networking, as some hosting providers require (in my case, OVH). In this scenario: * the host is a described below * the guest runs as HVM. * the guest runs exclusively with ioemu; virtual network drivers are not available (vanilla lenny guest, xen-vnif.ko does not exist, xen-netfront refuses to load despite the XenBus PCI device appearing) What xen/qemu-dm did is to build two network interfaces: * vifN.0 was used to send packets from the host to the guest routing was enabled towards this interface. No virtual hardware drivers took care of this network link, so all packets ended up dropped. * tapM was used by the guest to deliver packets from its virtual eth0. All packets were classified "martians" by the host and rejected. The reason why this happened is that the scripts/qemu-dm script *assumes* only bridging is ever used, and the scripts/vif-routing *assumes* only netfront is ever used. Here we have routing and ioemu, which causes the failure described above. -- Cyrille -- System Information: Debian Release: squeeze/sid APT prefers testing APT policy: (800, 'testing'), (600, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 2.6.26-1-xen-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages xen-utils-3.2-1 depends on: ii e2fslibs 1.41.9-1 ext2/ext3/ext4 file system librari ii iproute 20090324-1 networking and traffic control too ii libc6 2.9-25 GNU C Library: Shared libraries ii libgcrypt11 1.4.4-4 LGPL Crypto library - runtime libr ii libgnutls26 2.8.4-1 the GNU TLS library - runtime libr ii libncurses5 5.7+20090803-2 shared libraries for terminal hand ii libsdl1.2debian 1.2.13-2 Simple DirectMedia Layer ii libxenstore3.0 3.4.0-2 Xenstore communications library fo ii python 2.5.4-2 An interactive high-level object-o ii python-central 0.6.11 register and build utility for Pyt ii udev 146-5 /dev/ and hotplug management daemo ii xen-utils-common 3.3.1-2 XEN administrative tools - common ii zlib1g 1:1.2.3.3.dfsg-15 compression library - runtime Versions of packages xen-utils-3.2-1 recommends: ii bridge-utils 1.4-5 Utilities for configuring the Linu ii xen-hypervisor-3.2-1-amd64 [x 3.2.1-2 The Xen Hypervisor on AMD64 Versions of packages xen-utils-3.2-1 suggests: pn xen-docs-3.2 <none> (no description available) -- no debconf information -------------- next part -------------- An HTML attachment was scrubbed...

However there are still some issues with this config as discussed in http://lists.xen.org/archives/html/xen-users/2015-08/msg00003.html In your case (only EMU no PV at all) some of the gotchas described there ought to be avoided and the suggested change may well work.

[Pkg-xen-devel] Bug#554805: xen-utils-3.2-1: ioemu routed networking on HVM guests fails
tags 554805 + moreinfo thanks Hi Cyrille, This is about the bug report about networking for HVM guests that you filed before in the Debian bug tracker, against the Xen packages. Your bug report was targeted at a Xen package in a Debian distribution older than the current stable (Stretch). Can you please help us by confirming that any of the following scenarios does apply to your situation? * I had this problem a long time ago. It was never solved, but I found a workaround, which is ... * I had this problem a long time ago, and I solved it by not using Xen any more, but by doing ... * I still experience this problem, and I'm still using Xen 3.2/4.1/4.4/etc. I cannot upgrade to Debian Stretch or Buster because ... * I had this problem, and since upgrading to Stretch / Buster / ? it seems it was solved, and I forgot to report it again. Please close it, thanks. * Other: ... Note that even if you found a solution, it's still very useful to report it back to our bug tracker. There might be someone else running into the same problem, who can be helped with your information. Please note that unless there's a response within a month from now, we will close the bug report. If you discover this message later, and this case is important to you, then you can try unarchiving the bug and replying to it, or reach out to the maintainers email list at pkg-xen-devel at lists.alioth.debian.org (no subscription required) and post a message. Thanks, Hans van Kranenburg
