Packer Virtualbox builder, from json to hcl

# the source block is what was defined in the builders section and represents a
# reusable way to start a machine. You build your images from that source. All
# sources have a 1:1 correspondance to what currently is a builder. The
# argument name (ie: ami_name) must be unquoted and can be set using the equal
# sign operator (=).

# This file was autogenerated by the BETA 'packer hcl2_upgrade' command. We
# recommend double checking that everything is correct before going forward. We
# also recommend treating this file as disposable. The HCL2 blocks in this
# file can be moved to other files. For example, the variable blocks could be
# moved to their own 'variables.pkr.hcl' file, etc. Those files need to be
# suffixed with '.pkr.hcl' to be visible to Packer. To use multiple files at
# once they also need to be in the same folder. 'packer inspect folder/'
# will describe to you what is in that folder.

# All generated input variables will be of 'string' type as this is how Packer JSON
# views them; you can change their type later on. Read the variables type
# constraints documentation
# https://www.packer.io/docs/from-1.5/variables#type-constraints for more info.

# source blocks are generated from your builders; a source can be referenced in
# build blocks. A build block runs provisioner and post-processors on a
# source. Read the documentation for source blocks here:

#could not parse template for following block: "template: generated:3:317: executing \"generated\" at <.Name>: can't evaluate field Name in type struct { HTTPIP string; HTTPPort string }"
