A: Yes, but you must convert it first using the qemu-img convert command to VDI format.
The Ultimate Guide to Windows Vista QCOW2 Downloads for Virtualization
It's important to address the legal status of running Windows Vista in 2026. While Microsoft has ended official support for the OS, it is generally considered "abandonware" by many in the vintage computing community. However, this is a colloquial term, not a legal one. and has not been released into the public domain, meaning downloading it for free from third-party sites exists in a legal grey area.

– For sensitive data, Qcow2 can encrypt the virtual disk, protecting your files even if the image file is copied or stolen.
When the VM starts, it will boot from the ISO. Proceed with the normal Windows installation: accept the license, choose , select the unallocated space, and let the installer copy files. After the first reboot, the installation continues, and soon you will have a running Windows Vista guest. A: Yes, but you must convert it first

Vista’s Aero Glass interface requires 3D acceleration. Standard QCOW2 images run with a basic framebuffer, resulting in a sluggish experience. To enable Aero, the user must install the virtio-win-guest-tools or configure SPICE/QXL within the VM. Alternatively, using PCI passthrough for a legacy GPU is possible but complex. For most archival purposes, disabling Aero and using the “Windows Classic” theme yields acceptable performance for running legacy software.
