@yatin Hey, I think you might be confused with what this bug aimed to
do. The bug proposed that the `size` field should match the
`virtual_size` instead of the `size`. What we did to fix this was adding
a new `virtual_size` field that would represent the `virtual_size` value
in some of the images.

I don't think nova uses the `virtual_size` field but I should double
check. That said, the `virtual_size` value is an independent field that
has nothing to do with the `size` of the image. Therefore, I do not
believe these 2 fields should match. If anything, the virtual_size
should be as big or bigger than the image size.
