Openstack configuration (Release ONE)

Configure openstack for OSM (basic)

1 Create a valid tenant/user

You need to create a tenant/user with rights to create/delete images and flavors. One option is to use the admin tenant. Other options is to change the flavor/images management policies of your tenant/user at file /etc/nova/policy.json

2 Upload images. (optional). OSM will create the needed images into openstack at deploying, but the process takes a long time and the provided path at VNFD must be accesible by OSM (openmano). It is recomended to upload the image manually at openstack.

openstack image create --file="./cirros-0.3.4-x86_64-disk.img" --container-format=bare --disk-format=qcow2 --public --property location="/mnt/powervault/virtualization/osm/CirrOS/cirros-0.3.4-x86_64-disk.img" cirros034

Configure openstack for OSM (EPA)

1 Provide a mechanism to connect the SR-IOV interfaces. As they are physical ports connected to an external switch, Neutron will not be able to connect them. You can use a physical switch programmed to interconnect the vlan tags among them (not recommened for security reasons). Another solution is to use a ML2 plugin that programs the external switch.

2 Configure the Neutron controller for using SR-IOV ports:

Edit /etc/neutron/plugins/ml2/ml2_conf.ini with the tag and vlan ranges used by the dataplane network

[ml2_type_vlan] 
 network_vlan_ranges = physnet_sriov:3000:3100

3 Configure the compute nodes for using SR-IOV

On each compute node you have to associate the VFs available to each physical network. That is performed by configuring pci_passthrough_whitelist in /etc/nova/nova.conf. So, for example:

pci_passthrough_whitelist = {"vendor_id":"8086", "product_id":"10ed","physical_network":"physnet_sriov"} 

Add openstack at OSM

There is a parameter called --config used to suply general guidelines both at datacenter creation and datacenter association to openmano tenant (this later precedes)

openmano datacenter-create openstack-site http://10.10.10.11:5000/v2.0 --type openstack --description "OpenStack site" --config='security-groups: default, keypair: mykey' 
openmano datacenter-attach openstack-site --user=admin --password=userpwd --vim-tenant-name=admin --config='availavolity_zone: one'

The following configuration can be added:

• security_groups: to be used for the deployment
• availavolity_zone: to be used for the deployment
• keypair: to be added in addition to the keypair allocated on the VNF descriptor
• dataplane_physical_net: The configured network_vlan_ranges at neutron for SRIOV networks, e.g. 'physnet_sriov' in the above configurition
