During Windows installation, the setup will not see the VirtIO drive by default. You must:
Supports natively compressing data clusters and securing the virtual disk with AES encryption. Step-by-Step: How to Create a Windows 10 QCOW2 Image Windows 10.qcow2
Update the under the VM Options tab to make this disk the primary boot device. Method 3: Using Virt-Manager (GUI)
60G is the maximum virtual size (it will only take up a few megabytes initially). Step 3: Bootstrap Windows 10 via QEMU/KVM
Or with virsh (libvirt):
# Convert to VirtualBox (VDI) qemu-img convert -O vdi Windows\ 10.qcow2 Windows\ 10.vdi
Whether you are a DevOps engineer building a CI pipeline or a student learning Windows internals, mastering the Windows 10.qcow2 file is a skill that pays dividends in efficiency and storage savings. Fire up virt-manager , create your image, and join the thousands of developers running Windows 10 seamlessly on Linux today.
Install the virtio-win-guest-tools inside Windows. Also, allocate dedicated memory to the virtual GPU in virt-manager (e.g., 256MB of Video RAM). qemu-img create -f qcow2 -b windows10_base
As a deployment format for virtualized Windows 10, windows10.qcow2 offers strong flexibility, space efficiency, and useful features (snapshots, compression, encryption) at the cost of some performance overhead and management complexity. It’s a solid choice for development, testing, lab environments, and scenarios needing snapshot/versioning; for maximum raw performance in production, consider raw images on fast block storage or carefully tune QCOW2 usage (preallocation, caching, and storage backend).

Windows 10, when virtualized, benefits greatly from Qcow2 due to reduced storage overhead and flexible snapshot capabilities. Method 3: Using Virt-Manager (GUI) 60G is the
