Windows XP uses the old NTFS or FAT32 file systems, which do not natively understand modern SSD trimming. To prevent performance degradation, create your QCOW2 image with preallocation metadata enabled.
warn that modern antivirus software no longer supports XP, making it highly vulnerable. Always run it behind a virtualized firewall or keep the VM (remove the flags) if it does not strictly require internet access. virtio driver
Use the qemu-img tool to convert existing virtual disks to QCOW2: windows xp qcow2
On your host system, compress and commit the image back into a new, smaller QCOW2 file:
Note: Because QCOW2 is a dynamic format, the file will only take up a few megabytes initially and will grow as you install files. 🛠️ Recommended QEMU Launch Configuration
qemu-img snapshot -l ~/vms/winxp.qcow2
Use a tool like to slipstream the VirtIO SCSI/Block drivers directly into your Windows XP installation ISO. Expose the QCOW2 image as a VirtIO device during setup. Step 3: Launching the Installation via QEMU
With the VM off, run:
A 40 GB virtual drive only takes up the space Windows XP actually uses (around 2–3 GB initially). qemu-img snapshot -a before-update ~/vms/winxp
When installing, press F6 to load third-party SCSI drivers, pointing to the VirtIO SCSI driver on a floppy image or simulated ISO.
