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,
