nano server output

[fmontaldo]

Hi,

I run the packer template for the nano server in order to obtain a base image with 300MB. This are the latest lines of the build:

==> virtualbox-iso: Connected to WinRM!
==> virtualbox-iso: Uploading VirtualBox version info (5.2.16)
==> virtualbox-iso: Gracefully halting virtual machine...
virtualbox-iso: Removing floppy drive...

Build 'virtualbox-iso' finished.

Can someone help in order to configure the output of the image?.

Regards
