备注

在 Windows Server 2012 R2 中,虚拟机快照已重命名为 Hyper-v 管理器中的虚拟机检查点,以匹配 System Center 虚拟机管理中使用的术语。In Windows Server 2012 R2, virtual machine snapshots were renamed to virtual machine checkpoints in Hyper-V Manager to match the terminology used in System Center Virtual Machine Management. 有关详细信息,请参阅 检查点和快照概述For details, see Checkpoints and Snapshots Overview.

问题Issue

找到了具有一个或多个检查点的虚拟机。A virtual machine with one or more checkpoints has been found.

影响Impact

可用空间可能会在存储检查点文件的物理磁盘上运行。如果发生这种情况,则不能在物理存储上执行其他磁盘操作。依赖于物理存储的任何虚拟机都可能会受到影响。Available space may run out on the physical disk that stores the checkpoints files. If this occurs, no additional disk operations can be performed on the physical storage. Any virtual machine that relies on the physical storage could be affected.

如果物理磁盘空间不足,则在该磁盘上存储的检查点或虚拟硬盘的任何正在运行的虚拟机可能会自动暂停。If physical disk space runs out, any running virtual machine that has checkpoints or virtual hard disks stored on that disk may be paused automatically. Hyper-v 管理器将这些虚拟机的状态显示为 "暂停-关键"。Hyper-V Manager shows the status of these virtual machines as paused-critical.

解决方法Resolution

如果虚拟机在生产环境中运行服务器工作负荷,则使虚拟机脱机,并使用 Hyper-v 管理器应用或删除检查点。若要删除检查点,你必须关闭虚拟机以完成该过程。If the virtual machine runs a server workload in a production environment, take the virtual machine offline and then use Hyper-V Manager to apply or delete the checkpoints. To delete checkpoints, you must shut down the virtual machine to complete the process.

备注

现在,可以使用生产检查点作为标准检查点的替代方案。Production checkpoints are now available as an alternative to standard checkpoints. 有关详细信息,请参阅 在标准或生产检查点之间选择For details, see Choose between standard or production checkpoints.
