openstack 实例增加网卡
时间:2019-12-22 16:36 来源:csdn.net 作者:IT
openstack中某个实例新增加一个网卡有两种方式
一种是用通过openstack增加
这种增加不但会增加一个虚拟网卡，还会自动分配一个ip
##设置环境变量
source .admin_openrc.sh
##查看网络
neutron net-list
neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.

##增加网络端口
neutron port-create 763b1b5b-85d7-4101-a51b-d621931d15b8 ###可以指定ip哦

+--------------------------------------+-----------+----------------------------------+--------+------------+-------------+-------------------------+
##为实例增加端口=增加虚拟网卡
nova interface-attach --port-id 4dfaaf48-0fd0-4a9d-82eb-a2190c5b8ff4 706d5c3b-0511-4bbf-b101-e1780c893b79^C
另外一种是直接用virsh attach-interface 增加
这种增加方式是跳过openstack ，直接kvm 方式增加，这种是单单增加一个虚拟网口，如果需要配置ip，得进入虚拟机增加ip

nova list --all
