使用 qemu-img 工具创建 Windows 7 的 qcow2 磁盘。建议分配 50 GB 或更大的空间，以确保有足够的容量安装操作系统和应用软件。CSDN 上某篇 2021 年的实操文章中使用的是 15 GB，但也建议根据实际需求适当增加。

Utilize your hypervisor’s backup utilities to take regular, external snapshots of the QCOW2 file, ensuring rapid recovery in the event of guest OS compromise. If you want to customize your deployment further, tell me:

When creating the QCOW2 file via the command line, use modern allocation options to prevent performance degradation:
