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 .
