Re: [Rdo-list] Attempt to reproduce https://github.com/beekhof/osp-ha-deploy/blob/master/HA-keepalived.md

I understand that in usual situation , creating ifcfg-br-ex and ifcfg-eth2 ( as OVS bridge and OVS port) , `service network restart` should be run to make eth2 (no IP) OVS port of br-ex (any IP which belongs ext net and is available) What bad does NetworkManager when external network provider is used ? Disabling it, I break routing via eth0's interfaces of cluster nodes to 10.10.10.0/24 ( ext net), so nothing is supposed to work :- http://blog.oddbit.com/2014/05/28/multiple-external-networks-wit/ http://dbaxps.blogspot.com/2015/10/multiple-external-networks-with-single... Either I am missing something here. ________________________________________ From: rdo-list-bounces(a)redhat.com <rdo-list-bounces(a)redhat.com&gt; on behalf of Boris Derzhavets <bderzhavets(a)hotmail.com&gt; Sent: Friday, November 13, 2015 1:09 PM To: Javier Pena Cc: rdo-list(a)redhat.com Subject: [Rdo-list] Attempt to reproduce https://github.com/beekhof/osp-ha-deploy/blob/master/HA-keepalived.md Working on this task I was able to build 3 node HAProxy/Keepalived Controller's cluster , create compute node , launch CirrOS VM, However, I cannot ping floating IP of VM running on compute ( total 4 CentOS 7.1 VMs, nested kvm enabled ) Looks like provider external networks doesn't work for me. But , to have eth0 without IP (due to `ovs-vsctl add-port br-eth0 eth0 ) still allowing to ping 10.10.10.1, I need NetworkManager active, rather then network.service [root@hacontroller1 network-scripts]# systemctl status NetworkManager NetworkManager.service - Network Manager Loaded: loaded (/usr/lib/systemd/system/NetworkManager.service; enabled) Active: active (running) since Fri 2015-11-13 20:39:21 MSK; 12min ago Main PID: 808 (NetworkManager) CGroup: /system.slice/NetworkManager.service ├─ 808 /usr/sbin/NetworkManager --no-daemon └─2325 /sbin/dhclient -d -q -sf /usr/libexec/nm-dhcp-helper -pf /var/run/dhclient-eth0...

Eth0 would have to have static IP or dhcp lease, to provide route to 10.10.10.0/24. Thank you. Boris.
