Option A — Create a high-quality QCOW2 from an official Windows 11 ISO (recommended)

  1. Download the official Windows 11 ISO from Microsoft. Verify checksums.
  2. Create a new VM and install Windows 11 in raw format or directly into a QCOW2 backing file:
    • Use qemu-img to create a QCOW2:
      qemu-img create -f qcow2 windows11.qcow2 64G
      
    • Boot a QEMU VM with the ISO attached and perform a fresh install to that QCOW2 disk.
  3. Install virtio drivers (for KVM performance): attach the virtio ISO and install storage/network/gpu drivers inside Windows.
  4. Run Windows Update and install any required guest tools (spice guest tools, QEMU guest agent).
  5. Clean up before distributing or snapshotting: disable pagefile (optional), run disk cleanup, zero free space, and shrink the virtual disk if desired.
  6. Convert/compact the image (optional):
    • Zero free space inside Windows (sdelete -z) then on host:
      qemu-img convert -O qcow2 windows11.qcow2 windows11_compact.qcow2
      qemu-img compress windows11_compact.qcow2
      

Benefits: Trusted source, fully updatable, contains correct drivers, minimal surprises.

5. Evaluation of Pre-Built Images (Community Repositories)

If you must download a pre-built image rather than building one, use extreme caution. The most reputable community source is currently the Utomik or Dymatron repositories often referenced in Proxmox/KVM communities, but these are still "Community" level trust.

  • Recommendation: Use automated scripts like Automated-Windows-11-ISO-Creation (available on GitHub).
  • Why: These scripts download official files from Microsoft, inject drivers, and output a ready-to-use ISO or disk image. This provides the convenience of a download with the trust of an official source.

Step 3: Install Windows 11 with Optimal KVM Settings

Use virt-manager or this QEMU command snippet:

qemu-system-x86_64 \
  -enable-kvm \
  -cpu host \
  -smp 4 \
  -m 4096 \
  -drive file=win11.qcow2,if=virtio,aio=io_uring \
  -cdrom win11.iso \
  -netdev user,id=net0 -device virtio-net-pci,netdev=net0 \
  -machine q35 \
  -global ICH9-LPC.disable_s3=1

“Extra quality” enhancements:

  • Use virtio-scsi instead of IDE
  • Enable iothread for disk queues
  • Pass through kvm=off (hides hypervisor from some anti-cheat software)
  • Install VirtIO drivers during Windows setup (download from Fedora’s virtio-win ISO)

Where to start: source selection (prioritize safety and integrity)

  • Prefer official Microsoft installation media (ISO) as the primary source and convert or install into QCOW2 yourself for maximum trust.
  • For prebuilt QCOW2 images, prefer reputable virtualization communities, vendor pages, or well-known Linux distro maintainers that publish verified images.
  • Avoid unknown torrent sources or random downloads that lack checksums/signatures.

For Proxmox:

  • Cache: Write back (with UPS) or Write through (safer)
  • Discard: Enable (passes TRIM commands)
  • SSD emulation: Yes
  • IO thread: Separate for each disk
