Allow specifying --variant on the clonehd command!

[jwformat]

Would love to see an option to pass in additional options on clonehd... specifically looking for a --variant Fixed, but opening it up to allow any additional options would be awesome!

Failing that, any instructions for compiling this so I can put the change together myself?

Good suggestion. The VBoxManage command is hard-coded for now:

packer-post-processor-vhd/vhd/virtualbox.go

Lines 77 to 82 in a3b8ea5

	command := []string{
	"clonehd",
	"--format", "VHD",
	vmdk,
	outputPath,
	}

It should be possible to make that configurable, and use Go template strings to represent the path to VMDK and output path. Something like this:

{
  "post-processors": [
    {
      "type": "vhd",
      "only": ["virtualbox-iso"],
      "vboxmanage_command": ["clonehd", "--format", "VHD", "--variant", "Fixed", "{{ vmdkPath }}", "{{ outputPath }}"]
    }
  ]
}

I'm afraid I won't be able to implement that change, or something like it, for a little while.

Yep, it's very easy:

1. Install Go
2. Clone this repo
3. Add new arguments to the command above
4. Run make dist.

This project is basically complete, so I haven't touched it in a while. You might get some compilation errors. Happy to help you work through them.

Since I had a hard requirement for fixed size (when using VHD's), I grabbed the source, and was able to recompile with the hardcoded change in there. Just added an extra line into packer-post-process-vhd/vhd/virtualbox.go! Thanks for the suggestion, and the project!
