OpenMANO recap

Network scenario


OpenMANO addresses successfully network creation,

becoming a sound foundation for further automation

VNF AND NS DESCRIPTORS MAKE NETWORK DESIGN SIMPLE

EPA SUPPORT (NFVO & VIM)

PROPER VARIETY OF L2 CONNECTIVITIES

VNF ON-BOARDING DOES NOT REQUIRE FORMAL INTEGRATION

• Abstract models that hide complexity to

network engineer: just nodes and links

interconnecting them

• Allows to deploy for high performance

• Passthrough, SR-IOV, Virtio

• E-Line & E-LAN

• Descriptor-based (openly available)

VNF VNF

VNF VNF

E-Line E-LAN


• Low-end laptops/PCs

• Functional tests

• Low cost

OpenMANO minimizes entry barriers for VNF developers

LOCAL DEVELOPMENT

&TESTING

• Real servers and switches

• Performance tests (EPA

can be enforced)

• Cost-effective shared pool

SHARED POOL FOR

DEVELOPERS

• Production/pre-production

environment

• Real network scenarios

• Final service configuration

Hands-on session


Target

• Practice with openMANO

• Create and deploy a network scenario in a

local environment

(@host)

1. #kvm: list virtual machines defined at localhost

$ sudo virsh list

$ sudo virsh list --all

$ sudo virsh dumpxml openmano-centos

2.- #start openmano virtual machine

$ sudo virsh start openmano-centos

3.- #enter virtual machine

$ ssh [email protected] #password dpdk

Launching the controller node (openMANO)


OPENVIM (I)

Configuration & start

(@VM openmano-centos)

1. #openvim configuration

$ less openmano/openvim/openvimd.cfg

2. #openvim start

$ service-openmano openflow start #not used in development mode

$ service-openmano openvim start

#see openvim logs:

$ cat openmano/logs/openvim.0

3. #CLI configuration environment variables

$ openvim config

$ openvim –h


OPENVIM (II)

Add a compute host using a descriptor


4. #ensure that openvim has ssh access to the compute node without

any prompt (password, confirmation, ...)

#ssh key access are already inserted at host. Test it

ssh [email protected]

#if it fails, run “rm –f .ssh/known_hosts ”

ssh [email protected] #exit to go back to openmano-centos

5. #generate the compute node descriptor (not needed in this session)

# To generate the descriptor, a script is used:

$ ls openmano/scripts/host-add.sh

# The descriptor: numas, cores, interfaces, ...

$ less yamls/developer_host.yaml

6. #add the host to openvim

$ openvim host-add yamls/developer_host.yaml

$ openvim host-list

$ openvim host-list -vvv


OPENVIM (III)

Create external networks


7. #create external networks, to be used later in network

scenarios

$ cat yamls/virbrCon.yaml # A bridge to access to the VMs

$ cat yamls/default.yaml # libvirt default network (NAT-based)

$ openvim net-create yamls/virbrCon.yaml

$ openvim net-create yamls/default.yaml

$ openvim net-list

$ openvim net-list –vvv


OPENVIM (IV)

Create VIM tenant


8. #create VIM tenant

$ openvim tenant-create --name my_vim_tenant --description

"description"

$ openvim tenant-list

9. #configure openvim CLI to use the created tenant

$ openvim config

$ export OPENVIM_TENANT=<uuid>

$ echo "export OPENVIM_TENANT=<uuid>" >> .bashrc

$ openvim config


OPENMANO (I)

Configuration & start


1. #openmano configuration

$ less openmano/openmano/openmanod.cfg

2. #openmano start

$ service-openmano openmano start

# see openmano logs:

$ cat openmano/logs/openmano.0

3. #CLI configuration environment variables

$ openmano config

$ openmano –h


OPENMANO (II)

Create NFVO tenant


4. #create NFVO tenant

$ openmano tenant-create mytenant --description="description"

$ openmano tenant-list # write down the uuid

5. #configure openmano CLI to use this tenant

$ openvim config

$ export OPENMANO_TENANT=<uuid>

# add openmano environment variables to ~/.bashrc

$ echo "export OPENMANO_TENANT=<uuid>" >> .bashrc

$ openmano config


OPENMANO (III)

Add openvim datacenter


6. #creating datacenter 'mydc' in openmano

$ openmano datacenter-create mydc http://localhost:9080/openvim

$ openmano datacenter-list

$ openmano datacenter-list --all

7. #attach datacenter (openvim) and VIM tenant to the NFVO tenant

$ openmano datacenter-attach mydc --vim-tenant-id <vim_tenant_uuid>

$ openmano datacenter-list

$ export OPENMANO_DATACENTER=<datacenter_uuid>

#add openmano environment variables to ~/.bashrc

$ echo "export OPENMANO_DATACENTER=<datacenter_uuid>" >> ~/.bashrc

8. #update datacenter (openvim) external nets

$ openmano datacenter-net-update -f mydc

$ openmano datacenter-net-list mydc


OPENMANO (IV)

Add some VNFs


9. #insert 4 VNFs

$ openmano vnf-list

# see descriptors

$ less yamls/gateway.yaml

$ less yamls/l3forward.yaml

# add VNFs to openmano

$ openmano vnf-create yamls/gateway.yaml

$ openmano vnf-create yamls/l3forward.yaml

$ openmano vnf-create yamls/pktgen_1p.yaml

$ openmano vnf-create yamls/pktsink_1p.yaml

$ openmano vnf-list

$ openmano vnf-list -vvv


OPENMANO (V)

Add an NS definition and deploy it


10. #insert network scenarios

$ less yamls/scenario.yaml

$ openmano scenario-create yamls/scenario.yaml

$ openmano scenario-list

11. #launch the network scenario (it creates an instance)

$ openmano instance-scenario-list

$ openmano scenario-deploy dpdk_training dpdk_training

$ openmano instance-scenario-list

$ openmano instance-scenario-list dpdk_training

$ openvim vm-list


OPENMANO-GUI (I)

Configuration


1. #edit openmano-gui configuration

$ openmano tenant-list # write down the uuid

$ vi openmano/openmano-gui/config.php

# set 'mano_tenant' variable with the proper tenant


OPENMANO-GUI (II)

Usage

(@host)

2. #open firefox web browser

(http://10.10.0.3/openmano)

#scenarios

#VNF catalogue

#physical

#create new scenario


Check access to deployed virtual machines (I)

(@host)

1. #virtual machine list

$ sudo virsh list

$ sudo virt-manager

# enter gateway VM console

(@VM gateway)

2. #Getting gateway public IP address

$ ifconfig #Write down the gateway public IP address

# close console VM gateway


Check access to deployed virtual machines (II)

(@host)

3. Enter scenario VMs through the gateway

$ ssh dpdk@<gateway-public-ip> #password: dpdk

(@VM gateway) $ ssh 192.168.100.2 #pktgen #exit

(@VM gateway) $ ssh 192.168.100.3 #l3fwd #exit
