First, you must create a blank QCOW2 file that will act as the virtual hard disk. Open your terminal and run the following command to create a 40GB disk: qemu-img create -f qcow2 windows7.qcow2 40G Use code with caution. Step 2: Install Windows 7 with VirtIO Drivers

Load both the Windows 7 ISO and the VirtIO ISO.

While Microsoft officially ended extended support for Windows 7 in early 2020, the operating system remains a staple for legacy software compatibility, malware analysis, and specialized industrial applications. In 2021, the QCOW2 (QEMU Copy-On-Write)

qemu-system-x86_64 -hda windows7.qcow2 -cdrom path/to/windows7.iso -m 2048 -vnc :0 windows 7qcow2 2021

Execute the following QEMU command to map the Windows 7 ISO, the VirtIO driver disk, and your target QCOW2 image:

Windows 7 does not include VirtIO drivers out of the box. If you attempt to boot a standard Windows 7 ISO on a KVM hypervisor configured with VirtIO SCSI or VirtIO Block storage, the installer will throw a familiar error: "No drives were found. Click Load Driver to provide a mass storage driver for installation."

Example improved QEMU line:

qemu-img convert -f vmdk windows7.vmdk -O qcow2 windows7.qcow2
