Do you mean the code in qga/?  That is the QEMU guest agent.  It does
not have a command to create directories.

live-guestfs?  Never heard of it.

Do you mean libguestfs?  That's a tool for disk image manipulation.
Very powerful but works on offline guest disk images.  It does not work
while the guest is running.

The same network transports that you would use on a physical machine:
HTTP, CIFS, NFS.

Or an emulated device like a USB Mass Storage Device (like hot-plugging
a thumbdrive into a computer) or the experimental USB Media Transfer
Protocol emulation.
