If you need to create a fresh 40GB disk:
Windows 10 is designed for physical hardware and can feel sluggish in a virtual environment without proper tuning. Implement these adjustments to maximize performance. 1. Enable VirtIO Drivers
If you are using or virsh , your domain configuration should point to the .qcow2 file as a virtio device for the best performance.
Proceed through the Windows 10 installer until you reach the screen. The list will appear completely blank. Click Load driver -> Browse . Windows 10.qcow2
You can boot the VM using virt-install . This command mounts both the Windows 10 ISO and the VirtIO driver ISO simultaneously:
Ensure you are using hardware acceleration. The QEMU command should always include -enable-kvm . In virt-manager , this is automatically set when you select "Copy host CPU configuration".
Windows lacks native drivers for high-performance KVM virtual hardware. Download the latest stable virtio-win.iso from the official Fedora peer repository. Step 2: Provision the QCOW2 Disk If you need to create a fresh 40GB
Once your virtual disk is created, the next phase is installing Windows onto your new win10.qcow2 file.
Download the latest official installation media from the Microsoft Windows 10 Download Page.
chmod 644 Windows\ 10.qcow2
This is a virtual hard disk file containing a Windows 10 installation. The .qcow2 format is specific to the QEMU (Quick Emulator) hypervisor. Unlike standard .raw or .vhd files, QCOW2 files are "sparse"—they only take up the actual space used by data, not the total size of the virtual drive. It also supports features like snapshots and backing files, allowing you to save the state of the virtual machine at a specific point in time.
Built-in support for end-to-end encryption directly at the virtual disk layer.
While you can download pre-made images (more on that later), building your own ensures security and custom driver integration. Enable VirtIO Drivers If you are using or
qemu-img convert -f raw -O qcow2 windows_10.img windows_10.qcow2 Use code with caution. Optimizing Windows 10 QCOW2 Performance
Run the following command to boot from the ISO and install onto the qcow2 file:
