Packer always uploading guest additions iso?


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?


Hi, thanks for reaching out!. You should be able to turn this off using guest_additions_mode = "disable" in your template. Check out the docs for this feature here for more info!

Thanks, I will test!
