The qemu-img utility allows us to create, convert, and modify guest images.
In step 1, we used the -f flag specifying the image format; in this case, raw, the name of the image to be created and the size in gigabytes.
In step 4, we used the info subcommand to gather additional information about the existing image. Note how the disk size is showing as currently being zero. This is due to the fact that this is a blank image, not containing a filesystem. We are going to create one in the next recipe.
