Right or wrong so far?

You can use the `qemu-img` tool to create a file for the virtual harddrive. To the virtual machine, it will look like a real harddrive, so that you can install anything on it you could on a real harddrive, including Microsoft Windows. This 'container' does not contain configuration data of your VM though, just the disk contents.

Mind you I am not to trusting of my comprehension at this point in my reading.
Something about creating  "qemu.img" in the current directory. This file
will contain nothing but zeroes  (that really lost me)

If you use the raw, uncompressed format then for, e.g., a 4 GB virtual harddrive it will create a 4 GB file containing zeroes. This is similar to buying a new harddrive, which usually is empty (zeroed).

Once you've prepared such a drive image, you can boot the virtual machine and let the VM install the operating system from an installation medium (e.g., Windows DVD) to the drive image. This obviously is only necessary once; starting with the next boot, the VM can boot from the disk image.

HTH,

Andreas

If anyone out there can make sense of my enigma and point me to additional resource material
I would appreciate it.
