openstack 实例增加网卡
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.

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
