Hello everybody,
I also sent this email to bonding-devel@lists.sourceforge.net
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

# 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.

Any ideas?

Does this one really say mtu 900 instead of 9000?
Is your eth1 up?
Did you try non-kvm traffic over the bonding interface?
Is the switch in LACP mode?

No, it was mtu 9000 (sorry for the confusion)

Yes the Cisco switch is in LACP mode and I use intel nics.

I noticed that incoming IPv6 traffic doesn't work anymore, the br0
interface recieved the IPv6 IP and I can ping it on the local-host but
not from an other server, the IPv6 works again to moment I remove the
bonding.
Remember tcpdump does show traffic coming in and out the br0 device but
not the vnet0 device that is used for the kvm guest.
Kind regards,

Anybody? I?m still unable to use bonding lacp & bridge & vlans with
kvm guest in a 3.x kernel (2.6 is working fine)
