# Vates / XCP-ng 日跟踪 · 2026-09-07
> 日期：2026-09-07（Asia/Shanghai）。原料：archive/2026-09-07/vates/。消化 09-03 至 09-07（含 09-03 当日发布的 RISC-V 博文）。

## 摘要
- **新高信号（相对档案/09-03 摘要未充分写入）：Xen on RISC-V 在真实硬件跑通**（2026-09-03，HiFive Premier P550；系列尚未上游）。
- **XCP-ng 8.3 LTS August 2026 Updates #2**：存储/迁移修复（CBT+QCOW2 leaf-coalesce、LVM 元数据、稀疏迁移加速、迁移保留 VDI tags——文称利于 K8s 集成）；需重启；累计更新。
- 延续有效：XO 原生 MCP（6.2+）、XO 6.8（含官方 Veeam for XCP-ng）、August Updates #1、V2V（nbdkit+VDDK）。
- 看过：定价页、Compute/GPU 文档、NetBox 插件、六月/七月维护包、刷新安装 ISO。

### [Xen on RISC-V just ran on real hardware!](https://xcp-ng.org/blog/2026/09/03/xen-on-risc-v-just-ran-on-real-hardware/)

> Big milestone for the Xen on RISC-V effort: Xen now boots a guest domain on physical RISC-V hardware, not just QEMU. … Xen boots and launches a guest domain on a HiFive Premier P550, on real silicon. The board's CPU implements a pre-ratification draft of the RISC-V hypervisor extension, so Xen needed changes to run on it. The series is not upstream yet.

### [August 2026 Updates #2 for XCP-ng 8.3 LTS](https://xcp-ng.org/blog/2026/08/27/august-2026-updates-2-for-xcp-ng-8-3-lts/)

> New maintenance updates are available for XCP-ng 8.3 LTS. Host reboots are necessary as part of this update. … These new updates are all about bug fixes related to storage management. … Fix a leaf-coalesce failure that can occur with QCOW2-backed disks in some cases when Changed Block Tracking (CBT) is enabled. … Fix a case of LVM metadata corruption on a secondary host using block-based shared storage repositories (iSCSI, FC, etc). … Improve migration speeds for sparse QCOW2-backed VDIs … Preserve VDI tags during migration. This is a foundational fix for Kubernetes integration.

### [MCP meets Xen Orchestra](https://xen-orchestra.com/blog/mcp-meets-xen-orchestra/)

> With XO 6.2, we shipped … native support for the Model Context Protocol (MCP). Not a third-party plugin, not a community experiment: @xen-orchestra/mcp is a first-party module maintained by the Vates team as part of the Xen Orchestra codebase.

## 对基础档案的影响
- **写入 RISC-V**：工程里程碑（真机 guest），非产品 SKU；标注未上游。
- **LTS 维护**：8.3 仍活跃；#2 存储/迁移修复可记入「近期维护」一行。
- MCP / Veeam / V2V / 无 NVIDIA vGPU 等既有结论不变。
