, though these are primarily intended for cloud testing and may require specific drivers. 2. Create the QCOW2 Disk Image Once you have the ISO, use the tool to create the virtual hard drive container. qemu-img create -f qcow2 win7.qcow2 40G : A minimum of 30–40 GB is recommended for a standard installation. 3. Install Windows 7 via QEMU/KVM
sudo virt-install \ --name win7-prebuild \ --ram 4096 \ --disk path=windows7.qcow2,format=qcow2 \ --import \ --os-variant win7

A image file acts as a virtual hard disk for a virtual machine (VM). Unlike raw images, QCOW2 files are thin-provisioned, meaning they only take up the disk space actually used by the virtual machine, rather than the entire allocated size from the start.
