I have a chained together set of packer .hcl files which outputs and received .ovf files.
In the initial .hcl I define a VM with the guest additions information which is uploaded and installed.
For the other .hcl files I define a “virtualbox-ovf” source as input.
My issue is that building each .hcl seems to always download the VBoxGuestAdditions.iso and this takes a while.
Is there a reason that packer always downloads the guest additions to the VMs? I assumed it would only need to do it once during the first VM creation?
