Comment 17 for bug 997978

@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.
