Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance! ** Changed in: libvirt (Ubuntu Precise) Status: Confirmed => Fix Committed ** Tags added: verification-needed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1218959 Title: KVM virbr# no longer forwards multicast traffic by default (U12.04) Status in “libvirt” package in Ubuntu: Fix Released Status in “linux” package in Ubuntu: Fix Released Status in “libvirt” source package in Precise: Fix Committed Status in “linux” source package in Precise: Won't Fix Bug description: A recent kernel update (Apr 2013) has made it's way to U12.04.2 LTS (approx June-Aug 2013) and has stopped the (default) behaviour of automatically forwarding multicast traffic over virbr#. Some updates the bridge subsystem now, by default, disable multicast traffic without IGMP Querier being enabled on that bridge. The corresponding Fedora/RHEL bug tracks the progress/updates of this specific change in relation to Fedora. https://bugzilla.redhat.com/show_bug.cgi?id=880035 (I have yet to find a similar bug report in Ubuntu so I have created this bug to help the Ubuntu community identify multicast issues that may arise since April 2013 in U12.04 LTS and presumably other Ubuntu releases as backports are made and break regression testing.) Using the latest patches in U12.04.2 LTS this following addition, with some modifications, can be made to the udev rules will enable multicast on virbr# bridge: https://bugzilla.redhat.com/show_bug.cgi?id=880035#c38 While this is an improvement/correction to KVM bridge networking it has broken existing functionality in U12.04.2 LTS and broke regressed functionality that once worked. IMPACT: multicast is broken over libvirt bridges FIX: set a (new, introduced by a new kernel) toggle on the bridges TEST CASE: cat /sys/devices/virtual/net/virbr0/bridge/multicast_querier - if 0, then forwarding multicast will be broken. REGRESSION POTENTIAL: should be none. older kernels do not have the toggle, and failure to set it will be ignored To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1218959/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : email@example.com Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
