additional ip problem,

[novelx]

please help.

i use dedicatd server, successfully install DA on my centos 7.

adding additional ip on admin front end it works and ping ok for new ip.,
my problem is..
after reboot , i cant access my server.. so i reinstall again with fresh os centos 7 and DA as many time and try again..
still doesnt work..

i create support ticket.. its reply "You will need to use sysrcd to look into this as duplicating the interfaces will break the network."

I had the same problem on CentOS 7.1, my problem was solved by deactivating NetworkManager:

[root@server~]# systemctl stop NetworkManager.service
[root@server~]# chkconfig NetworkManager off
Note: Forwarding request to 'systemctl disable NetworkManager.service'.
rm '/etc/systemd/system/multi-user.target.wants/NetworkManager.service'
rm '/etc/systemd/system/dbus-org.freedesktop.NetworkManager.service'
rm '/etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service'
[root@server ~]#

If network manager is not running, try to first enable and start it, then stop it and disable it.
