@serge, thanks for your input. here Dom0 ifconfig, with 2 machines
running.
i setup br0 myself because the machines are running at hetzner, with
special addon IP's so the vm's can be reached from the outside.
(wiki.hetzner.de/index.php/KVM_mit_Nutzung_aller_IPs_-_the_easy_way) i
am also evaluating the problem with hetzner support to ensure its not
one of their routers in from of the Dom0.
vnet0, vnet1 are the bridges created by libvirt, but the vm have static
ip entries in /network/interfaces and are bound to br0 via libvirt.
