Nova与neutron交互nova命令先介绍一下nova命令中与网络相关的一些参数。指定网络启动虚机usage: nova boot [--flavor flavor] [--image image] [--image-with key=value] [--boot-volume volume_id] [--snapshot snapshot_id] [--min-count number] [--max-count number] [--meta key=value] [--file dst-path=src-path] [--key-name key-name] [--user-data user-data] [--availability-zone availability-zone] [--security-groups security-groups] [--block-device-mapping dev-name=mapping] [--block-device key1=value1[,key2=value2...]] [--swap swap_size] [--ephemeral size=size[,format=format]] [--hint key=value] [--nic net-id=net-uuid,v4-fixed-ip=ip-addr,v6-fixed-ip=ip-addr,port-id=port-uuid] [--config-drive value] [--poll] name其中，v4/6-fixed-ip不能单独配置，必须和net-id一起配置；在一个--nic中net-id与port-id只能选择一个。命令示例：根据Port-ID启动虚机：# neutron port-create accd72eb-2cd0-4961-ad67-d028c92e5254 --fixed-ip ip_address=0# nova boot --flavor 100 --image 18f8b6e1-a957-4d94-a3dd-eca757afdeb9 \ --nic port-id=10e7e093-156e-402b-9a45-ff8ab13dfb03 test_vm_1启动虚机时指定网络，指定IP：# nova boot --flavor 100 --image 18f8b6e1-a957-4d94-a3dd-eca757afdeb9 \ --nic net-id=accd72eb-2cd0-4961-ad67-d028c92e5254,v4-fixed-ip=0 test_vm_2创建多网络虚机：# nova boot --flavor 100 --image 18f8b6e1-a957-4d94-a3dd-eca757afdeb9 \ --nic net-id=accd72eb-2cd0-4961-ad67-d028c92e5254 \ --nic net-id= 2125e96e-d2a3-42b3-931f-5a90149d0f90 test_vm_3修改虚机网络nova支持对于active的虚机添加或删除网卡，对应命令如下：interface-attach Attach a network interface to a erface-detach Detach a network interface from a erface-list List interfaces attached to a server.用法：nova interface-attach [--port-id port_id] [--net-id net_id] [--fixed-ip fixed_ip] servernova interface-detach server port_id命令示例：绑定一个端口、网络或者IP地址到虚机：nova?interface-attach?06fd79d1-99a8-451d-955c-f466b8986f34?--port-id?c310babc-c833-4b10-9d76-78d60a58af98将port-id从虚机解绑：nova?interface-detach?8dd2fb5d-30a9-45c7-8931-ba039adcd20f??5138a9ce-7114-4126-82e8-8685a6aeccee查看虚机对应的Port端口：[root@node-82 ~]# nova interface-list f09c0b84-8e5a-4a3d-8da9-7d57d105e0
