On my lab, the nodes for Openstack present two eth interface, the first one (eno2) the single external network used as floating IP, then the other one (eno3) for the private network.



On Juju gui I've that:



neutron-gateway:
 bridge-mappings: physnet1:br-ex
 data-port: br-ex:eno2
neutron-api:
 flat-network-providers: physnet1


I've opened this post https://ask.openstack.org/en/question/119783/no-route-to-instance-ssh-and-ping-no-route-to-host/ to resolve the problem about the Ping and Ssh connection to my instance, but during same check I've seen this issue on neutron-gateway:



error: "could not add network device eno2 to ofproto (Device or resource busy)"


Maybe that is the cause of my first issue, but I don't understand how I can fix it.

    On my lab, the nodes for Openstack present two eth interface, the first one (eno2) the single external network used as floating IP, then the other one (eno3) for the private network.



    On Juju gui I've that:



    neutron-gateway:
     bridge-mappings: physnet1:br-ex
     data-port: br-ex:eno2
    neutron-api:
     flat-network-providers: physnet1


    I've opened this post https://ask.openstack.org/en/question/119783/no-route-to-instance-ssh-and-ping-no-route-to-host/ to resolve the problem about the Ping and Ssh connection to my instance, but during same check I've seen this issue on neutron-gateway:



    error: "could not add network device eno2 to ofproto (Device or resource busy)"


    Maybe that is the cause of my first issue, but I don't understand how I can fix it.

      On my lab, the nodes for Openstack present two eth interface, the first one (eno2) the single external network used as floating IP, then the other one (eno3) for the private network.



      On Juju gui I've that:



      neutron-gateway:
       bridge-mappings: physnet1:br-ex
       data-port: br-ex:eno2
      neutron-api:
       flat-network-providers: physnet1


      I've opened this post https://ask.openstack.org/en/question/119783/no-route-to-instance-ssh-and-ping-no-route-to-host/ to resolve the problem about the Ping and Ssh connection to my instance, but during same check I've seen this issue on neutron-gateway:



      error: "could not add network device eno2 to ofproto (Device or resource busy)"


      Maybe that is the cause of my first issue, but I don't understand how I can fix it.

      On my lab, the nodes for Openstack present two eth interface, the first one (eno2) the single external network used as floating IP, then the other one (eno3) for the private network.



      On Juju gui I've that:



      neutron-gateway:
       bridge-mappings: physnet1:br-ex
       data-port: br-ex:eno2
      neutron-api:
       flat-network-providers: physnet1


      I've opened this post https://ask.openstack.org/en/question/119783/no-route-to-instance-ssh-and-ping-no-route-to-host/ to resolve the problem about the Ping and Ssh connection to my instance, but during same check I've seen this issue on neutron-gateway:



      error: "could not add network device eno2 to ofproto (Device or resource busy)"


      Maybe that is the cause of my first issue, but I don't understand how I can fix it.

          update 26/03/19:



          On Juju gui I've that:



          neutron-gateway:
           bridge-mappings: physnet1:br-ex
           data-port: br-ex:eno2
          neutron-api:
           flat-network-providers: physnet1


          Before to make the deploy of Openstack I've changed data-port from br-ex:eno2 to br-ex:eno3



          neutron-gateway:
           bridge-mappings: physnet1:br-ex
           data-port: br-ex:eno3


          The issue on eno2 is been resolved but the ping to instance is still present.
