Hi Edy,
please find some config files below. I did the interface config only
through the oVirt GUI.
I mean by reordering that after every reboot some interfaces are not the
same as before. That means I need to change the cables after reboot.
[root at lxedna ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
# Generated by VDSM version 4.17.28-1.el7
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=dhcp
MTU=1500
DEFROUTE=yes
NM_CONTROLLED=no
IPV6INIT=no
[root at lxedna ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth1
# Generated by VDSM version 4.17.23-0.el7.centos
DEVICE=eth1
BRIDGE=Test-LAN-SW1
ONBOOT=yes
MTU=1500
NM_CONTROLLED=no
IPV6INIT=no
[root at lxedna ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth2
# Generated by VDSM version 4.17.23-0.el7.centos
DEVICE=eth2
BRIDGE=PC-LAN
ONBOOT=yes
MTU=1500
NM_CONTROLLED=no
IPV6INIT=no
Best regards
Christoph
