Nexus1000v Neutron 插件

---

概述

Nexus1000v Neutron 插件 v2 实现了 Neutron v2.0 API。

需求

• Cisco Nexus1000v for KVM Release 5.2(1)SK(2.2) (或更高版本)

配置

Nexus1000v Neutron 插件配置

• 应在主机上安装 MySQL。按照以下步骤初始化 MySQL（其中 $PASS = mysql 密码）

$ mysql -u root -p$PASS -e 'DROP DATABASE IF EXISTS cisco_neutron;'
$ mysql -u root -p$PASS -e 'CREATE DATABASE IF NOT EXISTS cisco_neutron;'
$ mysql -u root -p$PASS -e 'GRANT ALL ON cisco_neutron.* TO '$Neutron_User'@'%' IDENTIFIED BY '$Neutron_Pass';

• 编辑 /etc/neutron/neutron.conf 并将 provider 设置为

[DEFAULT]
core_plugin = neutron.plugins.cisco.network_plugin.PluginV2

[DATABASE]
sql_connection = mysql://<username>:<password>@<database_ip>:3306/cisco_neutron

• 编辑文件 /etc/neutron/plugins/cisco/cisco_plugins.ini 并根据需要注释掉

[CISCO_PLUGINS]

# (StrOpt) Period-separated module path to the plugin class to use for
# the Cisco Nexus switches.
#
#nexus_plugin = neutron.plugins.cisco.nexus.cisco_nexus_plugin_v2.NexusPlugin

# (StrOpt) Period-separated module path to the plugin class to use for
# the virtual switches on compute nodes.

vswitch_plugin = neutron.plugins.cisco.n1kv.n1kv_neutron_plugin.N1kvNeutronPluginV2

[cisco]

# Cisco Nexus Switch configurations.
# Each switch to be managed by Openstack Neutron must be configured here.
#
# Cisco Nexus Switch Format.
# [NEXUS_SWITCH:<IP address of switch>]
# <hostname>=<port>                 (1)
# ssh_port=<ssh port>               (2)
# username=<credential username>    (3)
# password=<credential password>    (4)
#
# (1) For each host connected to a port on the switch, specify the hostname
#     and the Nexus physical port (interface) it is connected to.
# (2) The TCP port for connecting via SSH to manage the switch. This is
#     port number 22 unless the switch has been configured otherwise.
# (3) The username for logging into the switch to manage it.
# (4) The password for logging into the switch to manage it.
#
# Example:
# [NEXUS_SWITCH:1.1.1.1]
# compute1=1/1
# compute2=1/2
# ssh_port=22
# username=admin
# password=mySecretPassword

# [N1KV:<IP address of VSM>]
# username=<credential username>
# password=<credential password>
#
# Example:
# [N1KV:2.2.2.2]
# username=admin
# password=mySecretPassword

[cisco_n1k]

# (StrOpt) Specify the name of the integration bridge to which the VIFs are
# attached.
#
# Example: integration_bridge = br-int

# (StrOpt) Name of the policy profile to be associated with a port when no
# policy profile is specified during port creates.
#
# Example: default_policy_profile = service_profile

# (StrOpt) Name of the policy profile to be associated with a port owned by
# network node (dhcp, router).
#
# Example: network_node_policy_profile = dhcp_pp

# (StrOpt) Name of the network profile to be associated with a network when no
# network profile is specified during network creates. Admin should pre-create
# a network profile with this name.
#
# Example: default_network_profile = network_pool

# (StrOpt) Time in seconds for which the plugin polls the VSM for updates in
# policy profiles.
#
# Example: poll_duration = 180

[database]

# (StrOpt) Connection to the neutron_l2network database
#
# connection = mysql://<credential username>:<credential password>@127.0.0.1/cisco_neutron?charset=utf8
# Example: connection = mysql://root:mySecretPassword@127.0.0.1/cisco_neutron?charset=utf8
