Right, I guess you'd see this with a real switch as well? Maybe have your guest send a packet out once in a while so the bridge can learn its MAC address (we do this after migration, for example).

Does this mean that it is not possible for having each tun device in a
seperate bridge that serves a seperate Vlan? We have experienced a
strange problem that we couldn't yet explain. Given this setup:

Guest Host kvm1 --- eth0 -+- bridge0 --- vlan1 \
               |                     +-- eth0
kvm2 -+- eth0 -/                     /
      \- eth1 --- bridge1 --- vlan2 +

When sending packets through kvm2/eth0, they appear on both bridges and
also vlans, also when sending packets through kvm2/eth1. When the guest
has only one interface, the packets only appear on one bridge and one
vlan as it's supposed to be.

Can this be worked around?

This is strange.  Can you post the command line you used to start kvm2?
