I am having problems configuring vlan provider network on a single node devstack install. i would like to know if provider network are even possible on a single node install, because VMs can communicate directly over br-int integration bridge and physical connection isn't even used. I have configured a separate br-pr bridge and added eth2 interface. I created a vlan provider network on a configured physnetpr physical connection that uses br-pr bridge. I have connected a laptop to eth2 interface and configured vlan 100 on its ethernet interface. I have a VM running on this provider network, but communication between VM and laptop does not seem to work. I should also mention that I have disabled security groups by setting OVS firewall to NoopFirewallDriver. When using wireshark to look at the packets, even ARP packets do not get to their destination. ARP packets from the laptop seem to come to int-br-pr interface and ARP packets from the VM seem to come phy-br-pr interface. Is what I am trying to do even possible?
