This is especially useful for those who have existing Windows virtual machines from other hypervisors and want to bring them into a KVM environment.

Start with the qemu-img command above, grab a Windows 11 ISO, and build your own master image. You’ll never go back to sluggish VMDKs again.

If you're on a Linux system with KVM support, QEMU is the tool to use. Most distributions have QEMU packages available through their package managers. You'll also need OVMF firmware files for UEFI support and a virtio-win driver ISO to enable high-performance virtual devices. Microsoft provides pre-built VMs for developers

Add virtio drivers and guest tools for performance:

Inside Windows, ensure TRIM is enabled to maintain QCOW2 performance over time:

Windows 11 is notorious for its strict hardware requirements: TPM 2.0, Secure Boot, and at least 4GB of RAM. Running it in a standard virtual machine often results in lag, storage bloat, and the dreaded "This PC can't run Windows 11" error. You’ll never go back to sluggish VMDKs again

The QCOW2 format is the native disk image format for QEMU and KVM. Unlike raw images, QCOW2 supports thin provisioning, allowing the file to grow dynamically as data is written. It also supports snapshots, AES encryption, and zlib compression.

For those looking for a more straightforward solution, several third-party websites offer pre-converted Windows 11 QCOW2 images for download. When choosing a source, ensure that it is reputable and trustworthy to avoid any potential security risks.
