When debugging a build (or maintaining an existing packer file), teach `packer build -debug` how to step through individual `boot_command`s in order to triage the packer template.
The ISO builders (parallels, qemu, virtualbox, and vmware) had too
much common code which needed to be maintained separately. This change
moves that code to a common ISO configuration.
I exposed TargetPath as a config file option "target_path". I don't like
the name, but it follows the naming convention. The purpose of TargetPath
stands unmodified, and it enables a fair amount of customization.
This adds config option prlctl_post for builder parallels-iso/pvm. It
allows additional prlctl commands to run after the VM has been shutdown
just before being exported.
Remove the redundant StepRemoveDevices and rely on the cleanup to be handled by:
* StepAttachParallelsTools.Cleanup
* StepAttachFloppy.Cleanup
* stepAttachISO.Cleanup
"guest_os_distribution" become deprecated and is not required anymore.
But if it is defined (in outdated templates),then the value will be copied to "guest_os_type" and warning will be displayed.
The IP address that the guest OS connect to download files from the
http_dir is determined by searching for a host interface with an IP
assigned. Now it is possible to use host_interfaces to select which
interfaces are searched.
