If "top" refers to a (a snapshot layer on top of a base image), this is a great way to test software without breaking your main install.
| Configuration | Sequential Read (MB/s) | Sequential Write (MB/s) | 4K Random Read (IOPS) | | --- | --- | --- | --- | | raw disk (passthrough) | 520 | 480 | 12k | | qcow2 (default cache=none) | 310 | 280 | 8k | | qcow2 (optimal: writeback+queues) | 490 | 450 | 11.5k |
Some popular use cases for running Windows 7 with qcow2 include:
Windows 7 prioritizes foreground apps. For a VM server, switch to Background Services: Control Panel → System → Advanced → Performance → Advanced → Adjust for best performance of Background services .
"Discard" or "Trim" enabled to keep the QCOW2 file size small. Troubleshooting Common Issues
Users wanted to run Windows 7 on virtualization platforms, and qcow2 became a popular choice for storing Windows 7 virtual disks. The combination of Windows 7 and qcow2 offered several benefits:
If you want, I can: produce command syntax/examples for the CLI, design the web UI mockups, or write a short spec for the snapshot integrity checks.
