By following this guide, your Windows 10 QCOW2 environment will remain compact, highly responsive, and easy to migrate across your virtualization infrastructure.
Ensure your drive configuration in libvirt includes: discard='unmap'

After Windows boots to the desktop, the real tuning begins to unlock near-native performance. Windows 10.qcow2
QEMU 4.0+ supports discard (trim):
Users on macOS often use .qcow2 files with tools like UTM to run Windows 10 at near-native speeds by leveraging ARM-based images.
