红帽全球峰会11.6. 将实例配置为使用中继
您必须将虚拟机实例操作系统配置为使用分配给子端口的 Red Hat OpenStack Platform (RHOSP)网络服务(neutron)的 MAC 地址。您还可以在子端口创建过程中将子端口配置为使用特定的 MAC 地址。
先决条件
如果要执行 Compute 节点的实时迁移，请确保为 RHOSP 部署正确设置 RHOSP 网络服务 RPC 响应超时。RPC 响应超时值可能因站点而异，它取决于系统速度。常规建议是为/100 中继端口至少设置 120 秒的值设为 120 秒。
最佳实践是测量 RHOSP 部署的中继端口绑定过程时间，然后正确设置 RHOSP 网络服务 RPC 响应超时。尝试保持 RPC 响应超时值较低，但也为 RHOSP 网络服务提供足够的时间来接收 RPC 响应。更多信息请参阅 第 11.7 节 “配置网络服务 RPC 超时”。
流程
使用 network trunk 命令检查
网络中继的配置。Example
$ openstack network trunk list- 输出示例
