How to configure the Open vSwitch bridge for OpenStack
Today, we are going to take a quick look at how to configure the Open vSwitch bridge for OpenStack:
- First, we have to install the Open vSwitch package with these commands:
# yum -y install centos-release-openstack-train # yum --enablerepo=centos-openstack-train,epel -y install openstack-neutron-openvswitch
Copy Code - Next, we have to start Open vSwitch with this command:
# systemctl start openvswitch
Copy Code - Then, enable the service with the following command:
# systemctl enable openvswitch
Copy Code - After that we have to confirm ovs-vsctl can talk to the OpenvSwtch service as seen below:
# ovs-vsctl show cbbdea93-7224-43ab-ae42-1777525549c1 ovs_version: "2.12.0"
Copy Code - Now, we have to install the Network script if it is not present in the /etc/sysconfig/ folder
# yum -y install network-scripts
Copy Code - Then, we have to disable NetworkManager and enable Network script:
# systemctl disable --now NetworkManager # systemctl enable network
Copy Code - Next, we will configure the physical interface as seen below:
# vim /etc/sysconfig/network-scripts/ifcfg-enp4s0f0 DEVICE=enp4s0f0 ONBOOT=yes TYPE=OVSPort DEVICETYPE=ovs OVS_BRIDGE=br-enp4s0f0?
Copy CodeRemember to replace the interface name.
- Then, we will create the Open vSwitch bridge configuration as seen below:
Remember to replace the interface name, IP address, subnet, Gateway, DNS1, and DNS2.
- Now, it is time to create the Open vSwitch bridge by mapping the bridge to the physical interface and restarting the network service:
# ovs-vsctl add-br br-enp4s0f0 # ovs-vsctl add-port br-enp4s0f0 enp4s0f0 && systemctl restart network
Copy Code - Finally, we have to verify the bridge as seen below:
# ovs-vsctl show # ip addr
Copy Code
