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.
