Verifying Open vSwitch Configuration
In order for the Compute VMs on one server to talk to the Compute VMs of another server, a physical NIC must be added to bridge "br-int". By default, ens34 is added automatically to bridge “br-int” after the stack-openstack command execution. This bridge is where all VMs virtual NICs are created upon starting up a VM.
To verifying Open vSwitch configuration:
