-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello everybody, I also sent this email to bonding-devel@xxxxxxxxxxxxxxxxxxxxx I spent ours debugging and finding out what points to the problem. I run kvm quests with bridged networking on a bonding lacp set-up, with the 2.6 kernel this has been working fine for years. But with the 3.x kernel this doesn?t work any more. Traffic comes out the KVM quests but doesn?t come in. If I disable bonding everything just works again. # working with 2.6 not working with 3.x cat /etc/network/interfaces auto lo iface lo inet loopback auto bond0 iface bond0 inet manual slaves eth0 eth1 bond-mode 4 bond-miimon 100 pre-up /sbin/ifconfig bond0 mtu 9000 auto br0 iface br0 inet dhcp bridge_fd 0 bridge_stp on bridge_ports bond0 # working with 3.x but no bonding!! cat /etc/network/interfaces auto lo iface lo inet loopback auto eth0 iface eth0 inet manual mtu 900 auto br0 iface br0 inet dhcp bridge_fd 0 bridge_stp on bridge_ports eth0 # uname -a Linux viktoriya 3.2.0-4-amd64 #1 SMP Debian 3.2.41-2+deb7u2 x86_64 GNU/Linux bridge-utils version 1.5-6 I already checked iptabls, ebtables there are no running rules and the bellow on zero or one doesn't make a difference either also disabling bridge_stp off or bridge_maxwait 0 doesn't seem to help. /bin/echo "0" > /proc/sys/net/bridge/bridge-nf-call-arptables /bin/echo "0" > /proc/sys/net/bridge/bridge-nf-call-ip6tables /bin/echo "0" > /proc/sys/net/bridge/bridge-nf-call-iptables Any ideas?
