openstack 指定创建 vm IP 地址
当前使用 vlan 网络架构
默认状态下创建 VM 利用 DHCP 进行 IP 地址分配
由于某些原因需要指定某些 VM 的 IP 地址, 那么可以参考下面方法执行操作
先获得 TENANT, NETWORK 信息, 然后创建对应的 PORT, PORT 可以指定使用某个 IP 地址, 之后在创建 VM 时候指定对应的 PORT就可以
获得 tenant id
[root@sh-zabbix-129023 ~(keystone_DEV)]# keystone tenant-list | grep DEV | 00f77483830d48e5aafba5880f5c437d | DEV | True |
获得 network 信息
[root@sh-zabbix-129023 ~(keystone_DEV)]# neutron net-list | grep DEV | 9106aee4-2dc0-4a6d-a789-10c53e2b88c1 | SH_DEV_NET | a42781d8-07fd-4744-8409-0b1b40750a71 10.198.192.0/18 |
创建新的 port
[root@sh-zabbix-129023 ~(keystone_DEV)]# neutron port-create --tenant-id 00f77483830d48e5aafba5880f5c437d --fixed-ip subnet_id=a42781d8-07fd-4744-8409-0b1b40750a71,ip_address=10.198.193.94 9106aee4-2dc0-4a6d-a789-10c53e2b88c1
