Symptoms


文章摘要:当恢复检查点用于虚拟机 (VM) 时,Hyper-V 主机之间的 Hyper-V 实时迁移可能会失败。


 

问题:
 

Virtual machine failed to generate VHD tree: 'Catastrophic failure'('0x8000FFFF'). 

Virtual machine failed to generate VHD tree: 'The system cannot find the file specified.'('0x80070002').

 

实时迁移失败并超时。事件查看器中位于“Applications and Services Logs\Microsoft\Windows”下面的 Hyper-V-VMMS 日志会报告源上的实时迁移超时或失败。尝试使用 PowerShell 删除恢复检查点可能会生成以下错误之一。

提醒:Hyper-V 备份解决方案通常使用 Hyper-V 恢复检查点来执行备份。Avamar 在执行备份时使用恢复检查点。
提醒:请勿为了解决本文中描述的症状而删除以下方面。”C:\ProgramData\Microsoft\Windows\Hyper-V\Groups\groupregistry.vmcx”。删除此文件可能会导致无法解决此问题。请拨打以下号码联系戴尔技术支持。

Cause

本文包含有关使用备份软件执行虚拟机备份时 Hyper-V 实时迁移期间可能发生的错误的信息。错误是“Virtual machine failed to generate VHD tree: 'Catastrophic failure'('0x8000FFFF').”以及“Virtual machine failed to generate VHD tree: 'The system cannot find the file specified.'('0x80070002')”。

Resolution

解决方案:


具有 ProSupport 或 ProSupport Plus 服务的戴尔客户应致电 800-456-3355 联系戴尔技术支持以获得帮助。否则,请致电 800-782-4362 联系 Dell Avamar 技术支持以获得帮助。
 

其它信息:

 

如果之前实时迁移的虚拟机不再在原始源节点上运行,则 Windows 无法删除检查点或虚拟机组。此孤立的检查点或虚拟机组可能会导致后续 Hyper-V 备份失败。由于孤立的虚拟机组的缘故,它还可能会阻止该虚拟机实时迁移到另一个群集节点。

 

在执行手动清理过程之前,请查看下面的 Microsoft URL。此知识库文章提供了解决方案,可解决因环境因素导致的实时迁移故障:

识别 Hyper-V 检查点类型

以下两个 PowerShell 命令示例可帮助确定检查点(也称为快照)的类型。

Hyper-V Manager 中显示的虚拟机检查点

标准检查点:在此示例中,将“TESTVM3”名称更改为客户环境中的虚拟机的名称。
