Hmm...what if you don't have root/administrator access? It could still work if
you are determined enough, but thats not the sort of thing you want to force
onto a beginner.

I agree. TFTP might be useful if qemu one day supports netbooting, though.

I agree, thats a very good idea.

Of course, that doesn't apply if you cant use SMB, as was this person's case.
(Does the SMB support in qemu even work on Windows hosts?)

Giving the TFTP write access is probably the way to go (iirc this person would
have used TFTP in lieu of FTP, except that write access was required which made
TFTP a non-option).
