                <br>
                Regarding this schema of Neutron [1], could you confirm
                which packet flow is the correct? <br>
                <br>
                We are considering that a virtual machine (VM1) sends
                packets to VM2, but both VMs are located in different
                compute nodes (PM1 and PM2). Both VMs are in the same
                virtual network.<br>
                Which is the flow, a or b?<br>
                <br>
                a) VM1 -> PM1 -> Networking node -> PM2 ->
                VM2<br>
                b) VM1 -> PM1 -> PM2 -> VM2<br>
                <br>
                Thanks <br>
