If you want to "produce content" from an existing Windows 8 machine (Physical-to-Virtual or P2V), you can use specialized tools.
The actual physical space consumed on your host drive. Cluster Size: Typically 64 KiB; affects I/O performance.
to install the display and network drivers for a smooth experience. Finding Pre-Built Images
Install the QXL graphics driver found under the qxl folder on the VirtIO ISO to enable screen resolution adjustments and smoother frame rates.
When the Windows 8 installation menu loads, follow these steps to find your QCOW2 disk: Select . windows 8 qcow2
Download the latest stable Fedora ( virtio-win.iso ).
Keep this ISO handy; you will mount it as a secondary virtual CD-ROM drive alongside your Windows 8 installation media. Step 3: Launching the Installation via QEMU/KVM
Launch the VM using QEMU. You must mount both the Windows ISO and the VirtIO driver ISO to ensure the installer can "see" the virtual disk. qemu-system-x86_64 -m
If you run out of space on your virtual drive, QCOW2 makes expansion simple. qemu-img resize windows8.qcow2 +10G If you want to "produce content" from an
This is a critical step. Windows does not include the virtio drivers necessary to communicate with QEMU's paravirtualized devices (disk, network, etc.). Without these, you will experience dramatically slower disk and network I/O.
qcow2 stands for "QEMU Copy-On-Write version 2". It is the default disk image format for QEMU/KVM and is widely used in professional virtualization platforms like Proxmox VE. Its key features make it ideal for this task:
Confirm Spice Guest Tools or QEMU Guest Agent are installed within Windows 8 to handle memory ballooning and clean shutdowns. 3. Space Efficiency & Maintenance
Some websites offer ready-to-run QCOW2 images. : to install the display and network drivers for
This will start a new QEMU session with the Windows 8 installation media attached. Follow the installation prompts to install Windows 8 on the qcow2 disk image.
QCOW2 images support a feature called "Discard." When you delete a file inside the Windows 8 VM, the QCOW2 format can signal the host filesystem to reclaim that space. This prevents the image from growing indefinitely.
While "raw" disk images offer slightly better absolute performance, QCOW2 brings high-end features that make managing an older OS like Windows 8 much easier:
