[Rdo-list] Attempt to reproduce Getting Started with Multi-Node OpenStack RDO Havana + Gluster Backend + Neutron VLAN by Andrew Lau on F20 (2)

Thu Jan 16 19:48:31 UTC 2014

Trying to reproduce :
 http://kashyapc.fedorapeople.org/virt/openstack/Two-node-Havana-setup.txt   

I stopped at following point :

  $ systemctl start openvswitch.service
  $ systemctl enable openvswitch.service

  $ systemctl enable neutron-ovs-cleanup.service

  $ ovs-vsctl add-br br-int

  $ cat <<EOF > /etc/sysconfig/network-scripts/ifcfg-eth1
  DEVICE=eth1
  BOOTPROTO=static
  NM_CONTROLLED=no
  ONBOOT=yes
  TYPE=Ethernet
  EOF    

  $ cat <<EOF > /etc/sysconfig/network-scripts/ifcfg-br-ex
  DEVICE=br-ex
  BOOTPROTO=static
  ONBOOT=yes
  IPADDR=192.169.142.140
  NETMASK=255.255.255.0
  GATEWAY=192.168.122.1
  EOF

  $ ovs-vsctl add-br br-ex
  $ ovs-vsctl add-port br-ex eth0
  $ 

  $ systemctl stop NetworkManager
  $ systemctl disable NetworkManager
  $ systemctl restart network
  $ systemct status network   # must be running

  > here

  Action (itself) :-

  $ cat <<EOF > /etc/sysconfig/network-scripts/ifcfg-eth1
  DEVICE=eth1
  BOOTPROTO=static
  NM_CONTROLLED=no
  ONBOOT=yes
  TYPE=Ethernet
  EOF    

  won't create second interface on VM. Something else supposed to be done.

  Otherwise, eth1 won't appear in ifconfig report as well as it
  won't appear in routing table.

Attempt `ifup eth1` reports error : device is not known to system .
