Hi all,

I am endeavoring to follow along with this page (linked from the Quickstart) on Liberty:


I get stuck pretty quickly as after having run the packstack installation as specified I don't have a /etc/sysconfig/network-scripts/ifcfg-br-ex file to edit (the page above specifically says it will already exist). When I do ip addr I can however see the interface:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:1a:4a:0f:18:00 brd ff:ff:ff:ff:ff:ff
    inet brd scope global dynamic eth0
       valid_lft 2582sec preferred_lft 2582sec
    inet6 2620:52:0:f18:21a:4aff:fe0f:1800/64 scope global noprefixroute dynamic 
       valid_lft 2591969sec preferred_lft 604769sec
    inet6 fe80::21a:4aff:fe0f:1800/64 scope link 
       valid_lft forever preferred_lft forever
3: ovs-system: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN 
    link/ether ce:09:f2:3c:0f:51 brd ff:ff:ff:ff:ff:ff
4: br-int: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN 
    link/ether ee:1e:ef:1b:7b:40 brd ff:ff:ff:ff:ff:ff
5: br-tun: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN 
    link/ether b2:24:e7:6f:f1:47 brd ff:ff:ff:ff:ff:ff
6: br-ex: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN 
    link/ether ae:45:c1:84:ab:42 brd ff:ff:ff:ff:ff:ff
    inet6 fe80::ac45:c1ff:fe84:ab42/64 scope link 
       valid_lft forever preferred_lft forever

Is this page actually up to date and expected to work with Liberty (it says it was tested with CentOS 7 but it's not clear with which OpenStack/RDO release)?
