If you need to deploy multiple images, you can automate the build process using tools like Cloudbase-Init.
sudo yum install qemu-kvm libvirt virt-install virt-manager
, as Windows 8.1 requires specific instruction sets (like CMPXCHG16B) that older emulated CPUs might lack. Networking : Ensure the network model is set to windows 81 qcow2 install
The default user-mode networking ( -net user ) works but has limitations. For better performance, use bridged networking or virtio-net with a tap interface. After installing VirtIO network drivers, change the model to virtio :
In your VM manager (like Virt-Manager or Proxmox), set the hard disk bus to VirtIO and the network device model to VirtIO . If you need to deploy multiple images, you
Set your VM to at least 4GB RAM and 2 CPU cores for a smooth experience. You can find detailed workstation setup guides on EVE-NG to help with resource planning. 2. Creating the QCOW2 Image
For those using Proxmox Virtual Environment, the process is streamlined through its web interface. Proxmox defaults to QCOW2 format for virtual disks, making it an ideal platform for Windows 8.1 guests. For better performance, use bridged networking or virtio-net
Windows 8.1 does not natively include VirtIO drivers for KVM storage controllers or network interfaces. If your VM crashes into a "No Bootable Device" loop or a Blue Screen of Death (BSOD), your disk controller is likely set to VirtIO instead of IDE/SATA without the proper drivers installed. How to inject drivers post-boot:
: When you reach the "Where do you want to install Windows?" screen, click Load Driver .
You need three essential components before starting the installation: 1. Download the Storage Media : Secure an official installation image.
