Yeah, I have the opposite problem - too much in the same file :-)

I want to be able to savevm, but some of my VMs don't have any qcow2
images (because I don't trust them for mission-critical VMs since
recent discussion, or because they are floppy-only or CD-only VMs with
no hard disk).

To enable savevm, at least according to docs, I have to have a qcow2
image somewhere.  So I add a redundant minimum-size unpartitioned
qcow2 hard disk and hope nobody minds...

That seems a bit hackish.  It would be nice if savevm could just write
to a named file and loadvm could read it.
