  • Host: Intel i5-8250U, 16GB RAM, NVMe SSD
  • Standard Win10 (4GB RAM, VHDX): Boot time 45 seconds; idle RAM 2.8GB.
  • Windows 10 Lite Qcow2 (2GB RAM): Boot time 12 seconds; idle RAM 780MB.
  • Disk footprint: 5.2GB actual on host (thin provisioned).

A Qcow2 file only uses space on the host machine when the guest OS actually writes data, meaning a 60GB virtual disk might only take up 10GB on your physical drive. Snapshots: This format supports Live Snapshots Pros: Instant use; drag-and-drop into Proxmox or KVM
