Open Stack

Hello,

Yes. I was reading mostly
http://docs.openstack.org/networking-guide/scenario_legacy_lb.html
because imho this is what I want now :). I don't want DVR and L3 HA (at
least for now) but only traffic via vxlan between two vms which are
connected to tenant network (it is probably called east-west traffic,
yes?)
