红帽全球峰会19.5. 对 RHOSP 网络服务的高可用性(HA)更改
Red Hat OpenStack Platform (RHOSP) Networking 服务(neutron) API 已更新，以便管理员在创建路由器时设置-- ha=True/False 标志，这将覆盖 /var/lib/config-data/puppet-generated/neutron/etc/neutron/neutron.conf 中 l3_ha 的默认配置。
高可用性(HA)变为 neutron-server：
- 第 3 层(L3) HA 随机分配活跃角色，无论网络服务使用的调度程序是什么（随机还是最小路由器）。
- 数据库架构已被修改，以处理为虚拟路由器分配虚拟 IP 地址(VIP)。
- 创建传输网络来直接 L3 HA 流量。
HA 对网络服务 L3 代理的更改：
- 添加了一个新的 keepalived 管理器，提供负载均衡和 HA 功能。
- IP 地址转换为 VIP。
