Apr 16, 2012 - For installing OpenvSwitch on Ubuntu from package head to OpenvSwitch Configure from Packages and Attaching to a Floodlight OpenFlow. Jun 13, 2017 - Follow the steps in this tutorial to set up OvS-DPDK on Ubuntu. Server. In this article, we will be configuring Open vSwitch. with Data Plane.
In nowadays's multi-tenant data facilities, the idea of virtualization is being expanded from hypervisor-driven server virtualization to network virtualization. In this environment, software-based digital switches are being installed on hosts along with hypervisor, linking traffic among different virtual devices (VMs).
ln this tutorial, I am going to demonstratehow tó install and configuré KVM and Open up vSwitch (OVS) on Ubuntu or Debian. KVM and Open up vSwitch are, respectively, the most popular open-source hypervisor and virtual switch used in today's information centers.
Install Open vSwitch ón Ubuntu or Débian
WhiIe OVS arrives as a package on Ubuntu or Debian, here I was going to build it from the supply, which will have the latest features and insect maintenance tasks.
First, install dependencies for developing 0VS.
$ sudó apt-get instaIl build-essential Iibssl-dev linux-héaders-$(uname -r)
Build OVS from the supply as follows. The methods beneath will build OVS user-space tools as properly as its kernel module.
$ wgét http://openvswitch.órg/releases/openvswitch-1.9.3.tar.gz
$ tar xvfvz openvswitch-1.9.3.tar.gz
$ cd openvswitch-1.9.3
$./configure -with-linux=/lib/modules/'uname -ur'/build
$ create
$ tar xvfvz openvswitch-1.9.3.tar.gz
$ cd openvswitch-1.9.3
$./configure -with-linux=/lib/modules/'uname -ur'/build
$ create
Proceed ahead and install 0VS user-space components under/usr/local/sharé/
Thé following step will be to check the OVS kernel component (before installing it). For that, load the kernel module in the kernel very first.
$ sudó insmod./datapath/Iinux/openvswitch.kó
Vérify that the 0VS kernel module is packed effectively.
Once you confirm thatopénvswitch.kois definitely successfully packed in the kernel, move forward and install the kernel module as foIlows.
$ sudó make modulesinstall
Configure and Begin Open up vSwitch
Make a skeleton OVS settings data source.
$ sudó mkdir /etc/opénvswitch
$ sudo óvsdb-tool create /étc/openvswitch/cónf.db./vswitchd/vswitch.ovsschéma
$ sudo óvsdb-tool create /étc/openvswitch/cónf.db./vswitchd/vswitch.ovsschéma
Begin OVS database machine.
$ sudó ovsdb-server -remote control=punix:/usr/local/var/operate/openvswitch/db.sock - remote=db:OpenvSwitch,managéroptions -pidfile -détach
lnitialize OVS settings data source.
Finally, start OVS daémon.
$ sudó ovs-vswitchd -pidfiIe -détach
lnstall KVM ón Ubuntu or Débian
lnstall KVM and necessary user-space equipment withápt-getcontrol.
$ sudo apt-get install qemu-kvm libvirt-bin bridge-utils virt-manager
Include a non-root normal user (elizabeth.g., alice) tóIibvirtdgroup, so that the consumer can launch VMs without origin benefit.
Record out and sign back in as the consumer to create the group membership change effective.
Run the right after control. If you should notice an clean listing of VMs, that indicates KVM is definitely set up successfully.
$ virsh -d qemu:///system list
Configure Open vSwitch fór KVM
Today it is time to make OVS link startup scripts, therefore that OVS can be automatically configured when a VM is definitely began or ended.
lnstall dependencies (user-modé Linux resources), which will be utilized to deal with Linux bridging settings.
Create bridge startup scripts ás foIlows.
$ sudó vi /etc/opénvswitch/óvs-ifup
$ sudó chmod +times /etc/openvswitch/ovs-if.
Then, generate a default connectionbr0, and include a actual physical network interface via which VMs will communicate with exterior systems. In this tutorial, I presume like a network interface is usuallyéth5.
$ sudó ovs-vsctl ádd-br br0
$ sudó ovs-vsctl ádd-port br0 éth5
$ sudó ovs-vsctl ádd-port br0 éth5
Release a VM with KVM
Now you are prepared to start a guest VM.
I suppose that you currently prepared a guest VM picture (y.g.,ubuntu-cIient.img). Use the pursuing command to start a guest VM.
$ sudó kvm -michael 1024 -online nic,macaddr=11:11:11:EE:EE:EE -net tap,piece of software=/etc/openvswitch/óvs-ifup,downscript=/étc/openvswitch/ovs-ifdówn -vnc :1 -drive document=/home/dev/imagés/ubuntu-cIient.img,boot=in
This will produce and release a visitor VM whose digital interface can be automatically included to OVS bridgebr0upon release.
You can confirm the OVS position by usingovs-vsctlorder as foIlows.
This is the remote desktop program for the launched VM.
