openstack 例項增加網絡卡
阿新 • • 發佈：2019-01-09
openstack中某個例項新增加一個網絡卡有兩種方式
一種是用通過openstack增加
這種增加不但會增加一個虛擬網絡卡，還會自動分配一個ip
##設定環境變數
source .admin_openrc.sh

neutron net-list neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead. +--------------------------------------+-------------+----------------------------------+------------------------------------------------------+ | id | name | tenant_id | subnets | +--------------------------------------+-------------+----------------------------------+------------------------------------------------------+ | 763b1b5b-85d7-4101-a51b-d621931d15b8 | selfservice | 6f4b66aa95e84d7191d989a940830a95 | 936bc613-2c2c-447e-9936-137e3cd182fc 172.16.1.0/24 | | e035ec48-c7b7-414b-bc0c-117f0900e915 | provider | 6f4b66aa95e84d7191d989a940830a95 | 3bc9c2bf-d4ed-4e61-88d5-2be2b4cc073e 192.168.96.0/21 | +--------------------------------------+-------------+----------------------------------+------------------------------------------------------+

這種增加方式是跳過openstack ，直接kvm 方式增加，這種是單單增加一個虛擬網口，如果需要配置ip，得進入虛擬機器增加ip
