The guest is probably issuing I/O. Are there Windows tools you can use to see which process or kernel component is issuing I/O? You can try running qemu-img check <image-file> to ensure that the qcow2 file is consistent. Error messages will be printed if there are leaks or corruptions in the qcow2 file. Stefan
