This document describes how to install OpenStack plug-ins including SeerEngine-DC Neutron plug-ins, Nova patch, openvswitch-agent patch, and DHCP failover components on CentOS.

SeerEngine-DC 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.

SeerEngine-DC Neutron plug-ins are developed for the SeerEngine-DC controller based on the OpenStack framework. SeerEngine-DC 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 SeerEngine-DC Neutron plug-ins can provide the following features for tenants:

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

· SeerEngine-DC Neutron L3_Routing—Allows tenants to forward traffic to each other at Layer 3.

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

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

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

CAUTION:

To avoid service interruptions, do not modify the settings issued by the cloud platform on the controller, such as the virtual link layer network, vRouter, and vSubnet settings after the plug-ins connect to the OpenStack cloud platform.

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.

In specific scenarios (such as a vCenter network overlay scenario), you must install the Nova patch to enable 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 issue, you must install the openvswitch-agent patch.

DHCP failover components

DHCP component

I n the network-based overlay scenario, only a controller is currently allowed to assign addresses to virtual machines or bare metal servers as a DHCP server. When the controller is disconnected from the southbound network, the virtual machines or bare metal servers will not be able to renew and reobtain addresses through DHCP. To resolve the issue, you can install a DHCP component on a network node to provide DHCP failover in the network-based overlay scenario. When the controller loses connection to the southbound network, the virtual machines or bare metal servers can renew and reobtain addresses through the independently deployed DHCP server.

Metadata component

In the DHCP failover scenario, you must install a Metadata component on the network node to provide the Metadata function for the DHCP component.

Preparing for installation

Hardware requirements

Table 1 shows the hardware requirements for installing the SeerEngine-DC Neutron plug-ins, Nova patch, or openvswitch-agent patch on a server or virtual machine.

Table 1 Hardware requirements

CPU	Memory size	Disk space
Single-core and multicore CPUs	2 GB and above	5 GB and above

Software requirements

You can install the SeerEngine-DC Neutron plug-ins or Nova patch on OpenStack Pike that is deployed on CentOS 7.2.1511 with YUM.

IMPORTANT:

To install OpenStack plug-ins, the dnsmasq version must be 2.76. You can use the dnsmasq –v command to display the dnsmasq version number.

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.

NOTE:

For the installation of converged version of SeerEngine_DC plug-ins (SeerEngine_DC_PLUGIN-version-py2.7.egg or SeerEngine_DC_PLUGIN-version.noarch.rpm), see H3C SeerEngine-DC OpenStack Converged Plug-Ins Installation Guide.

Restrictions and guidelines

This document describes interoperability between SeerEngine-DC with one OpenStack platform that contains one controller node. In other scenarios, follow these restrictions and guidelines:

· SeerEngine-DC interoperates with one OpenStack platform that contains multiple controller nodes.

Configure all controller nodes on the OpenStack platform in the same way a single controller is configured, and make sure the configuration on all controller nodes is the same.

· SeerEngine-DC interoperates with multiple OpenStack platforms.

Make sure the cloud platform name (cloud_region_name) and VXLAN VNI for each OpenStack platform, and the host name for each node are unique across the OpenStack platforms.

If OpenStack is deployed in Yum mode under CentOS, SeerEngine-DC Neutron plug-ins or Nova patches can be installed in OpenStack Pike (CentOS 7.2.1511).

Installing OpenStack plug-ins

Install the SeerEngine-DC Neutron plug-ins on an OpenStack controller node, the Nova patch and openvswitch-agent patch on an OpenStack compute node, and the DHCP failover components on a network node. Before installation, you must install the Python tools on the associated node.

Installing the Python tools

Before installing the plug-ins, first you must 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 SeerEngine-DC Neutron plug-ins

Obtaining the SeerEngine-DC Neutron plug-in installation package

The SeerEngine-DC Neutron plug-ins are included in the SeerEngine-DC OpenStack package. Obtain the SeerEngine-DC 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 SeerEngine-DC 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 SeerEngine-DC Neutron plug-ins:

1. Access the directory where the SeerEngine-DC OpenStack package (an .egg or .rpm file) is saved, and install the package on the OpenStack controller node.

Installing/removing/upgrading DHCP failover components

To provide DHCP failover in the network-based overlay scenario, you must install DHCP failover components.

IMPORTANT:

The DHCP failover components can operate only on the CentOS 7.2.1511 operating system with a kernel version of 3.10.0-327.el7.x86_64. If the kernel version does not match that of the S1020V, install the kernel patch first .

Installing basic components

1. Install WebSocket Client on the controller and network node.

IMPORTANT:

Make sure the WebSocket Client version is 0.56.

[root@localhost ~]# yum install –y python-websocket-client

2. Install an S1020V vSwitch on the network node and configure bridge and controller settings. For the installation and configuration procedures, see H3C S1020V Installation Guide.

[root@localhost ~]# rpm -ivh --force s1020v-centos71-3.10.0-229.el7.x86_64-x86_64.rpm

3. Stop the open-source DHCP and Metadata services on OpenStack.

[root@localhost ~]# systemctl stop neutron-dhcp-agent neutron-metadata-agent

[root@localhost ~]# systemctl disable neutron-dhcp-agent neutron-metadata-agent

Obtaining the installation package of the DHCP failover components

Two SeerEngine-DC OpenStack packages are available: one contains the DHCP failover components package and one does not. The SeerEngine-DC OpenStack package that contains the DHCP failover components package is named in the SeerEngine_DC_PLUGIN-DHCP_version1_ pike_2017.10.egg format. version1 represents the software package version number.

Obtain the required version of the SeerEngine-DC OpenStack package and then save the package to the target installation directory on the server or virtual machine. You can also 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 DHCP failover components on the network node

Configuring the open-source metadata service for network nodes

OpenStack supports obtaining metadata from network nodes for VMs through DHCP or L3 gateway. H3C supports only the DHCP method. To configure the metadata service for network nodes:

1. Download the OpenStack installation guide from the OpenStack official website and follow the installation guide to configure the metadata service for the network nodes.

2. Configure the network nodes to provide metadata service through DHCP.

a. Use the vi editor to open configuration file dhcp_agent.ini.

[root@network ~]# vi /etc/neutron/dhcp_agent.ini

b. Press I to switch to insert mode, and modify configuration file dhcp_agent.ini as follows:

force_metadata = True

Set the value to True for the force_metadata parameter to force the network nodes to provide metadata service through DHCP.

c. Press Esc to quit insert mode, and enter :wq to exit the vi editor and save the dhcp_agent.ini configuration file.

Comparing and synchronizing resource information between the controller and cloud platform

NOTE:

This function is not supported in the following scenarios:

· Network overlay VXLAN environment with compute node neutron-cas-ovs-agent, neutron-cas-sriov-agent, neutron-vmware-ovs-agent, or f5-oslbaasv2-agent.

· CloudOS and third-party cloud platforms except for Ericsson.

· VPC connections except for those provided by H3C-proprietary plug-ins.

1. Execute the h3c-sdnplugin-extension compare --file [absolute path] file name.csv command to compare resource information between the controller and cloud platform.

¡ If you do not specify --file [absolute path] filename.csv, the comparison result is saved to the /var/log/neutron/compare_data-time.csv file, where time indicates the comparison start time.

¡ If you specify --file [absolute path] filename.csv, the comparison result is saved to the specified file. If you do not specify an absolute path, the result is saved to /var/log/neutron/file name.csv.

The comparison result file contains the following fields:

¡ Resource—Resource type.

¡ Name—Resource name.

¡ Id—Resource ID.

¡ Tenant_id—Tenant ID of the resource.

¡ Tenant_name—Tenant name of the resource.

¡ Status—Comparison result.

- lost—Less resources on the controller. You must add resources to the controller.

- different—Different resources on the controller than the cloud platform. You must update resources on the controller.

- surplus—More resources on the controller. You must remove excessive resources from the controller.

2. Execute the h3c-sdnplugin-extension sync –file comparison result file name.csv command. If the comparison result file is in the /var/log/neutron/ path, enter the file name directly. If the comparison result file is in another path, enter the absolute file path.

After the command is executed, the system displays resource statistics and prompts for your confirmation to start the synchronization. The system starts the synchronization only after receiving your confirmation for twice.

After the synchronization is complete, a synchronization result file /var/log/neutron/sync_all-time.csv is generated, where time indicates the synchronization start time.

CAUTION:

· Do not add or edit information in the synchronize result file.

· To avoid anomaly caused by misoperations, examine and compare the result file and resource statistics carefully.

FAQ

The Python tools cannot be installed using the yum command when a proxy server is used for Internet access. What should I do?

Configure HTTP proxy by performing the following steps:

1. Make sure the server or the virtual machine can access the HTTP proxy server.

2. At the CLI of the CentOS system, use the vi editor to open the yum.conf configuration file. If the yum.conf configuration file does not exist, this step creates the file.

[root@localhost ~]# vi /etc/yum.conf

3. Press I to switch to insert mode, and provide HTTP proxy information as follows:

¡ If the server does not require authentication, enter HTTP proxy information in the following format:
proxy = http://yourproxyaddress:proxyport

¡ If the server requires authentication, enter HTTP proxy information in the following format:
proxy = http://yourproxyaddress:proxyport
proxy_username=username
proxy_password=password

Table 3 describes the arguments in HTTP proxy information.

Table 3 Arguments in HTTP proxy information

Field	Description
username	Username for logging in to the proxy server, for example, sdn.
password	Password for logging in to the proxy server, for example, 123456.
yourproxyaddress	IP address of the proxy server, for example, 172.25.1.1.
proxyport	Port number of the proxy server, for example, 8080.

proxy = http://172.25.1.1:8080

proxy_username = sdn

proxy_password = 123456

4. Press Esc to quit insert mode, and enter :wq to exit the vi editor and save the yum.conf file.

The Inter X700 Ethernet network adapter series fails to receive LLDP messages. What should I do?

Use the following procedure to resolve the issue. An enp61s0f3 Ethernet network adapter is used as an example.

1. View and record system kernel information.

[root@localhost ~]# uname -r

3.10.0-957.1.3.el7.x86_64

2. View detailed information about the Ethernet network adapter and record the values for the firmware-version and bus-info fields.

[root@localhost ~]# ethtool -i enp61s0f3

driver: i40e

version: 2.8.20-k

firmware-version: 3.33 0x80000f0c 1.1767.0

expansion-rom-version:

bus-info: 0000:3d:00.3

supports-statistics: yes

supports-test: yes

supports-eeprom-access: yes

supports-register-dump: yes

supports-priv-flags: yes

3. Use one of the following solutions, depending on the kernel version and network adapter firmware version:

¡ The kernel version is higher than kernel-3.10.0-957.el7 and the network adapter firmware version is 4 or higher.

# Execute the following command:

[root@localhost ~]# ethtool --set-priv-flags enp61s0f3 disable-fw-lldp on

# Identify whether the value for the disable-fw-lldp field is on.

[root@localhost ~]# ethtool --show-priv-flags enp61s0f3 | grep lldp

disable-fw-lldp : on

If the value is on, the network adapter then can receive LLDP messages. For this command to remain effective after a system restart, you must write this command into the user-defined startup program file.

# Open the self-defined startup program file.

[root@localhost ~]# vi /etc/rc.d/rc.local

# Press I to switch to insert mode, and add this command to the file. Then press Esc to quit insert mode, and enter :wq to exit the vi editor and save the file.

ethtool --set-priv-flags enp61s0f3 disable-fw-lldp on

# Configure the file to be executable.

[root@localhost ~]# chmod 755 /etc/rc.d/rc.local

¡ The kernel version is lower than kernel-3.10.0-957.el7, or the network adapter firmware version is lower than 4.

# Execute the echo "lldp stop" > /sys/kernel/debug/i40e/bus-info/command command. Enter the recorded bus info value for the network adapter, and add a backslash (\) before each ":".

[root@localhost ~]# echo "lldp stop" > /sys/kernel/debug/i40e/0000\:3d\:00.3/command

The network adapter can receive LLDP messages after this command is executed. For this command to remain effective after a system restart, you must write this command into the user-defined startup program file.

# Open the self-defined startup program file.

[root@localhost ~]# vi /etc/rc.d/rc.local

# Press I to switch to insert mode, and add this command to the file. Then Press Esc to quit insert mode, and enter :wq to exit the vi editor and save the file.

echo "lldp stop" > /sys/kernel/debug/i40e/0000\:3d\:00.3/command

# Configure the file to be executable.

[root@localhost ~]# chmod 755 /etc/rc.d/rc.local
