Inside the virtual machine, mount the virtio-win.iso and run virtio-win-guest-tools.exe . This installs: VirtIO Network Drivers (for higher network throughput). Ballooning drivers (for efficient memory management). QEMU guest agent (for better management). B. Compress the Image
: You can re-compress the image to make it easier to share.
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. windows 8 qcow2
Once Windows is running, you should finalize the setup to improve stability: Device Manager
qemu-system-x86_64 -hda windows8.qcow2 -cdrom /path/to/windows8.iso -m 2048 -vga virtio Inside the virtual machine, mount the virtio-win
If you have a Windows 8 installation in another format (like VHD or VMDK), you can convert it to QCOW2 using qemu-img .
: You can create a "base" Windows 8 image and spin up multiple linked VMs that only store the differences from that base, saving massive amounts of storage. How to Create a Windows 8 QCOW2 Image QEMU guest agent (for better management)
Are you a Linux user who needs to run Windows 8 for work or personal reasons? Do you want to experience the best of both worlds without dual-booting or using a virtual machine with a hefty footprint? Look no further than qcow2, a powerful and versatile disk image format that allows you to run Windows 8 on Linux with ease.
If the system becomes unstable, revert to your restore point using: qemu-img snapshot -a clean_install windows8.qcow2 Use code with caution. Compacting the Image
If you are using virt-manager , this can be set by editing the VM's hardware details and changing the disk's "Cache mode" under Advanced Options.
