Package: libvirt0 Version: 5.0.0-1 Severity: grave Justification: renders package unusable
Dear Maintainer, After a recent upgrade, IPv6 communication between a virtual router and another virtual client over an isolated network stopped working. I am seeing the rotuer advertisments sent by the router on vnet0, which is attached to the bridge virbr1, but when I capture packages on the bridge, the IPv6 traffic is gone. It just took me several hours of debugging to realize that the reason for this is that /proc/sys/net/ipv6/conf/virbr1/disable_ipv6 is set to 1. After setting it to 0, IPv6 is working as expected now. This is a regression, IPv6 used to work between virtual clients just fine without having to manually fiddle with the network configuration. Kind regards, Ralf -- System Information: Debian Release: buster/sid APT prefers testing APT policy: (990, 'testing'), (500, 'unstable-debug'), (500, 'testing-debug'), (100, 'unstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.19.0-2-amd64 (SMP w/8 CPU cores) Kernel taint flags: TAINT_USER, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages libvirt0 depends on: ii libacl1 2.2.52-3+b1 ii libapparmor1 2.13.2-7 ii libaudit1 1:2.8.4-2 ii libavahi-client3 0.7-4+b1 ii libavahi-common3 0.7-4+b1 ii libc6 2.28-7 ii libcap-ng0 0.7.9-2 ii libcurl3-gnutls 7.64.0-1 ii libdbus-1-3 1.12.12-1 ii libdevmapper1.02.1 2:1.02.155-2 ii libgcc1 1:8.2.0-21 ii libgnutls30 3.6.6-2 ii libnl-3-200 3.4.0-1 ii libnl-route-3-200 3.4.0-1 ii libnuma1 2.0.12-1 ii libsasl2-2 2.1.27+dfsg-1 ii libselinux1 2.8-1+b1 ii libssh2-1 1.8.0-2 ii libxml2 2.9.4+dfsg1-7+b3 ii libyajl2 2.1.0-3 Versions of packages libvirt0 recommends: ii lvm2 2.03.02-2 libvirt0 suggests no packages. -- no debconf information
