When launching QEMU via the command line, use the following disk arguments:

-device usb-tablet : Absolutely essential. It synchronizes the host and guest mouse pointers, preventing the annoying "double cursor" lag. Step 4: Post-Installation Upgrades for Top Performance
| Feature | Benefit for Windows Workloads | |--------|--------------------------------| | | Quickly roll back Windows Updates or driver installs. | | Thin Provisioning | Allocate 100GB virtual space but only use actual disk blocks. | | Compression | Reduce storage footprint for idle Windows VMs. | | Encryption (LUKS + Qcow2) | Secure sensitive Windows data at rest. | | Backup Efficiency | Use qemu-img for incremental backups without agent software. | windows+xpqcow2+top
If your interest lies in managing or monitoring performance on a system with these aspects:
Boot XP, let it detect the new VirtIO storage controller, and install the viostor driver from the legacy VirtIO ISO. Shut down the VM again.
One of the most common frustration points when installing Windows XP onto a QCOW2 image is the "Hard disk not recognized" error. Because the Windows XP installer lacks native support for drivers, it cannot see the virtual hard disk during the initial "blue screen" text-mode setup. When launching QEMU via the command line, use

Even the fastest XPQCow2 disk is useless if Windows misbehaves. | | Thin Provisioning | Allocate 100GB virtual
