In this post, we’ll break down what a Windows 10.qcow2 file is, why you should use it, and how to get your Windows 10 VM running smoothly.

To generate a Windows 10 QCOW2 image, you typically use qemu-img to create a virtual disk and then install Windows from an ISO file. QCOW2 (QEMU Copy-On-Write) is the standard storage format for virtual disks in QEMU and KVM. 1. Create a Blank QCOW2 Image

Instead of using a generic virtual CPU, use -cpu host to pass through the specific instructions of your physical processor.
