To install Windows 10 directly onto the QCOW2 image, launch QEMU via the CLI or use virt-manager . The command below mounts the Windows installer, attaches the VirtIO driver ISO as a secondary CD-ROM, and enables hardware acceleration.

Take a snapshot of your clean Windows 10 installation setup: qemu-img snapshot -c clean_install win10.qcow2 Use code with caution. To list all available snapshots within the file: qemu-img snapshot -l win10.qcow2 Use code with caution. To revert to the clean install state: qemu-img snapshot -a clean_install win10.qcow2 Use code with caution.

Start by creating a virtual disk container using the QEMU Command Line Tools : qemu-img create -f qcow2 windows10.qcow2 50G Use code with caution. 2. The VirtIO Driver Requirement

Virtualizing Windows 10 in a Linux environment requires an efficient virtual disk format. The QEMU Copy-On-Write version 2 (QCOW2) format is the standard choice for KVM (Kernel-based Virtual Machine) hypervisors. Unlike raw disk images, QCOW2 supports thin provisioning, snapshots, and AES encryption. The command below mounts the Windows installer, attaches

What kind of are you using? (NVMe SSD, SATA SSD, or mechanical HDD?)

: Ensure the disk bus is set to VirtIO rather than SATA or IDE.

Enable the discard mount option to allow the guest OS to tell the QCOW2 file to shrink when files are deleted inside Windows. Converting ISO or VMDK to QCOW2

Qcow2 needs extra free space to commit changes when merging. Solution: Ensure at least 10 GB free on the host filesystem before deleting a large snapshot.
