Right-click it, choose , and browse the VirtIO CD-ROM drive.
: Once the driver is loaded, your 40GB QCOW2 disk will appear. Continue the installation as normal. 4. Post-Installation

You must boot the VM using the Windows ISO and the VirtIO Driver ISO simultaneously. Right-click it, choose , and browse the VirtIO CD-ROM drive
Preallocation reserves space for metadata upfront, reducing fragmentation and improving throughput. Without preallocation, QCOW2 performance falls significantly behind raw formats; with preallocation, the difference is minimal.

: Attach the Windows 8.1 ISO to one CD-ROM drive and the VirtIO ISO to a second CD-ROM drive. Step 3: The Windows 8.1 Installation Process
This is the most critical step for performance. When the installer asks where to install Windows and shows no drives:
Windows installer won’t show the disk if virtio drivers aren’t loaded:
Installing Windows 8.1 on a image via QEMU is a standard process that involves creating a virtual disk, booting from an ISO, and potentially loading VirtIO drivers for better performance. 1. Create the qcow2 Disk Image First, use the tool to create a virtual hard drive. A
