You need QEMU to know about one disk which is in qcow2 format,
so it can save the state there, but that disk doesn't actually
have to be attached to the emulated machine. This blog post has
a note on how to do that:
(look for the bit starting "If the QEMU system you’re trying to debug
doesn’t have a disk image at all".)
