Pino, do you remember what the missing data was that prevents
virt-builder from working properly with SimpleStreams?
IIRC it was the target (expanded) size of the image, as it means we
don't know during the planning stage if we will need to resize the
image.
Almost: if no --size is specified for virt-builder, then the template
is used as-is; when specifying --size, there is a size check to error
out on shrinking, and to pass the right size to virt-resize.
Currently we use the "size" (which represents the size of the image)
also as size of the image: this implies that the shrinking check won't
actually work properly, causing a failure.
We also miss the information about the partition to expand, so
virt-resize merely adds a new empty partition at the end to fill the
extra space.
