Openvswitch + ACS networking
Hi,
I am trying to setup ACS with openvswitch for advanced networking, but I cannot really understand the openvswitch+ACS networking part.
I have a kvm host with 2 nics and I want to use nic1 for management+storage traffic, and nic2 for public+guest traffic.
So I use the following
ovs-vsctl add-br cloudbr0
ovs-vsctl add-port cloudbr0 eth0
ovs-vsctl add-br cloudbr1
ovs-vsctl add-port cloudbr1 eth0
then for ifcfg-eth0
DEVICE=eth0
HWADDR=00:04:xx:xx:xx:xx (My MAC addr)
ONBOOT=yes
HOTPLUG=no
BOOTPROTO=none
TYPE=Ethernet
then for ifcfg-eth1
DEVICE=eth1
HWADDR=xx:xx:xx:xx:xx:xx (my MAC addr)
ONBOOT=yes
HOTPLUG=no
BOOTPROTO=none
TYPE=Ethernet
for ifcfg-cloudbr0:
DEVICE=cloudbr0
ONBOOT=yes
HOTPLUG=no
BOOTPROTO=static
DEVICETYPE=ovs
TYPE=OVSBridge
IPADDR=172.16.0.10
GATEWAY=172.16.0.1
NETMASK=255.255.255.0
for ifcfg-cloudbr1:
DEVICE=cloudbr1
ONBOOT=yes
HOTPLUG=no
BOOTPROTO=static
DEVICETYPE=ovs
TYPE=OVSBridge
Later on the Web GUI I create two physical networks:
Physical Network 1 where I add management and storage (blue and red buttons) with traffic label ‘cloudbr0’ and VLAN type
Physical Network 2 where I add public and guest (green and yellow buttons) with traffic label ‘cloudbr1’ and GRE type
my ip-ranges are:
pod: 172.16.0.100 - 110
public: 172.16.0.200 - 210
guest: vlan 1000-1100
storage: 172.16.0.50 - 60
After the ACS installation it is obvious that there is no communication between the management server and the system vms.
What is wrong with my setup?…

Hi Andrija,
this was really a good reading but I only have 2 nics and I cannot use bonds.
Also, regarding this article I have one more question:
while the article in the OVS part describes four nics eth0 / eth1 / eth2 / eth3 in the output of the 'ovs-vsctl show' command the bonds include different interfaces
e.g the bond0 has eth1 and veth1. Why is this happening?
best regards,
Po
