While RAW images offer slightly faster raw read/write speeds, QCOW2 is generally preferred for Windows 8 virtual machines (VMs) due to several distinct advantages:

Windows 8 QCOW2 images remain valuable for legacy application support, testing, and archival use. However, they require deliberate handling: ensure licensing compliance, use VirtIO drivers for acceptable performance, harden and isolate the guest due to limited support, and follow disciplined image creation and snapshot practices. For production or performance-sensitive use, evaluate whether upgrading to a supported Windows release or moving workloads to containerized or cloud-native alternatives is feasible; when migration isn’t possible, rigorous operational controls around QCOW2-based Windows 8 VMs will mitigate most risks. qemu-img create -f qcow2 windows8
Boot the VM and proceed to the screen.
If you have an existing Windows 8 virtual machine running on VMware or Hyper-V, you can easily migrate it to QCOW2 format using qemu-img :
Windows does not natively include storage or network drivers for KVM. You must download the official stable VirtIO ISO to ensure the Windows installer can detect the QCOW2 disk: wget https://fedorapeople.org Use code with caution. 3. Creating the Windows 8 QCOW2 Virtual Disk
