This document describes how to install the virtual converged framework (VCF) Neutron plug-ins, Nova patch, and openvswitch-agent patch that are compatible with OpenStack on CentOS.

VCF Neutron plug-ins

Neutron is a type of OpenStack services used to manage all virtual networking infrastructures (VNIs) in an OpenStack environment. It provides virtual network services to the devices managed by OpenStack computing services.

VCF Neutron plug-ins are developed for the SeerEngine-DC controller based on the OpenStack framework. VCF Neutron plug-ins can obtain network configuration from OpenStack through REST APIs and synchronize the configuration to the SeerEngine-DC controllers. They can obtain settings for the tenants' networks, subnets, routers, ports, FW, LB, or VPN. Different types of VCF Neutron plug-ins can provide the following features for tenants:

· VCF Neutron Core plug-in—Allows tenants to use basic network communication for cores, including networks, subnets, routers, and ports.

· VCF Neutron L3_Routing—Allows tenants to forward traffic to each other at Layer 3.

· VCF Neutron FWaaS plug-in—Allows tenants to create firewall services.

· VCF Neutron LBaaS plug-in—Allows tenants to create LB services.

· VCF Neutron VPNaaS plug-in—Allows tenants to create VPN services.

Nova patch

Nova is an OpenStack computing controller that provides virtual services for users. The virtual services include creating, starting up, shutting down, and migrating virtual machines and setting configuration information for the virtual machines, such as CPU and memory information.

The Nova patch enables virtual machines created by OpenStack to access networks managed by SeerEngine-DC controllers.

Openvswitch-agent patch

The open source openvswitch-agent process on an OpenStack compute node might fail to deploy VLAN flow tables to open source vSwitches when the following conditions exist:

· The kernel-based virtual machine (KVM) technology is used on the node.

· The hierarchical port binding feature is configured on the node.

To resolve this problem, you must install the openvswitch-agent patch.

IMPORTANT:

Before you install the OpenStack plug-ins, make sure the following requirements are met:

· Your system has a reliable Internet connection.

· OpenStack has been deployed correctly. Verify that the /etc/hosts file on all nodes has the host name-IP address mappings, and the OpenStack Neutron extension services (Neutron-FWaas, Neutron-VPNaas, or Neutron-LBaas) have been deployed. For the deployment procedure, see the installation guide for the specific OpenStack version on the OpenStack official website.

Installing OpenStack plug-ins

The VCF Neutron plug-ins, Nova patch, and openvswitch-agent patch can be installed on different OpenStack versions. The installation package varies by OpenStack version. However, you can use the same procedure to install the Neutron plug-ins, Nova patch, or openvswitch-agent patch on different OpenStack versions. This document uses OpenStack Pike as an example.

Install the VCF Neutron plug-ins on an OpenStack controller node and install the Nova patch and openvswitch-agent patch on an OpenStack compute node. Before installation, you need to install the Python tools on the associated node.

Installing the Python tools

Before installing the plug-ins, first you need to download the Python tools online and install them.

To download and install the Python tools:

1. Update the software source list.

[root@localhost ~]# yum clean all

[root@localhost ~]# yum makecache

2. Download and install the Python tools.

[root@localhost ~]# yum install –y python-pip python-setuptools

Installing the VCF Neutron plug-ins

Obtaining the VCF Neutron plug-in installation package

The VCF Neutron plug-ins are included in the VCF OpenStack package. Obtain the VCF OpenStack package of the required version and then save the package to the target installation directory on the server or virtual machine.

Alternatively, transfer the installation package to the target installation directory through a file transfer protocol such as FTP, TFTP, or SCP. Use the binary transfer mode to prevent the software package from being corrupted during transit.

Installing the VCF Neutron plug-ins

CAUTION:

The QoS feature will not operate correctly if you configure the database connection in configuration file neutron.conf as follows:

[database]

connection = mysql://…

This is an open source bug in OpenStack. To prevent this problem, configure the database connection as follows:

[database]

connection = mysql+pymysql://…

The three dots (…) in the command line represents the neutron database link information.

Some parameters must be configured with the required values as described in "Parameters and fields."

To install the VCF Neutron plug-ins:

1. Access the directory where the VCF OpenStack package (an .egg file) is saved, and install the package on the OpenStack controller node. The name of the VCF OpenStack package is SeerEngine_DC_PLUGIN-version1_version2-py2.7.egg. version1 represents the version of the package. version2 represents the version of OpenStack.

In the following example, the VCF OpenStack package is saved to the path /root.

[root@localhost ~]# easy_install SeerEngine_DC_PLUGIN-E3108_pike_2017.10-py2.7.egg

2. Change the user group and permissions of the plug-in file to be consistent with those of the Neutron file.

[root@localhost ~]# cd /usr/lib/python2.7/site-packages

[root@localhost ~]# chown -R --reference=neutron SeerEngine*

[root@localhost ~]# chmod -R --reference=neutron SeerEngine*

[root@localhost ~]# cd /usr/bin

[root@localhost ~]# chown -R --reference=neutron-server h3c*

[root@localhost ~]# chmod -R --reference=neutron-server h3c*

3. Install the VCF Neutron plug-ins.

[root@localhost ~]# h3c-vcfplugin controller install
