<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>
Miguel.<br>
