Overview of the Issue

Hi, I am trying to create a new image, but I am getting the following behavior:

When specifying the image_min_disk, I would expect to see what the description says, "Minimum disk size needed to boot image, in gigabytes"; instead, I am setting the disk size.

image_min_disk and image_min_ram are not available. Instead, the current option should be named image_size.

It also takes a very long time to save the image, maybe due to the image size.

Reproduction Steps
