基于Ubuntu2504部署OpenStack E版

OpenStack Epoxy 巩固了作为 VMware 替代方案的地位，增强了安全性，并改进了硬件支持

第 31 版的亮点包括 Nova 中 PCI 直通的改进、Watcher 中添加新的 Prometheus 数据源以及 Manila 中的新安全功能。
随着 OpenStack 社区发布第 31 个版本 2025.1 Epoxy，OpenStack 的采用率正在飙升。 来自 BBC 研发中心、暴雪娱乐、Canonical、Cleura、爱立信、Mirantis、NVIDIA、Rackspace、Red Hat 和三星 SDS 等机构的约 450 名贡献者构建了 Epoxy，提供了超过 7,600 项变更和广泛的维护更新。此版本发布正值 OpenStack 社区成立 15 周年之际 。自2010 年以来，OpenStack 已提交超过 940,000 项变更，并已投入生产 4,500 万个核心，OpenStack 仍然是最活跃的开源项目社区之一。

• 强化OpenStack作为VMware的替代方案
  Watcher 中新增了 Prometheus 数据源。对于 VMware 迁移，通过 Watcher 将 Prometheus 集成到 OpenStack 中，可以高效监控现有的 VMware 基础架构和迁移过程。这可以跟踪迁移过程中的性能并识别瓶颈。
  此版本包含许多 Cinder 支持的存储硬件驱动程序的功能和错误修复，包括 NetApp、PowerMax、LightBits、Fujitsu、PowerFlex、3par、StorPool、Pure Storage、Nimble 和 Hitachi。对各种 Cinder 驱动程序的改进支持意味着简化了严重依赖特定存储解决方案的工作负载的迁移。此外，迁移后，OpenStack 环境可以保持与现有存储基础架构的兼容性，从而使过渡更加顺畅，并降低与存储和数据可访问性相关的风险。

• 增强安全性
  Manila 用户现在可以修改共享访问规则的访问级别，将其从“只读”切换为“读写”，反之亦然。此功能可以更精确地控制哪些用户可以修改和访问共享资源。如果用户可以将其访问权限限制为只读，则可以防止未经授权的修改，从而降低数据被意外或恶意更改的风险。
  马尼拉用户现在还可以通过共享网络子网元数据设置和修改共享服务器特性。云管理员可以通过 driver_updatable_subnet_metadata 配置选项定义允许的修改内容。此项改进可实现更好的网络隔离和分段，确保不同的数据集或应用程序被隔离在不同的子网中，从而降低发生违规时网络内部横向移动的风险。
  在 Octavia 中，用户现在可以将自定义 Neutron 安全组与 Octavia Amphora 负载均衡器 VIP 端口结合使用。通过将特定安全组与负载均衡器的 VIP（虚拟 IP）端口关联，您可以确保只有特定类型的流量才能到达负载均衡器，从而降低未经授权访问的风险。

• 提高硬件支持能力
  Ironic 新增了一个接口，支持将 bootc 容器镜像直接部署到主机，无需任何中间步骤。这降低了复杂性，使运维人员和最终用户的部署流程更加简化。
  Nova 的 PCI 直通功能现已支持新的内核 vfio-PCI 变体驱动程序，例如 Ubuntu 24.04 上的 Nvidia GRID。操作员现在可以使用这些特定的 PCI 设备创建实例并进行实时迁移，从而增强 OpenStack 支持 AI 工作负载的能力。
