~> **Warning:** The qemu command line allows extreme flexibility, so beware
of conflicting arguments causing failures of your run. For instance, using
--no-acpi could break the ability to send power signal type commands (e.g.,
shutdown -P now) to the virtual machine, thus preventing proper shutdown. To see
the defaults, look in the packer.log file and search for the qemu-system-x86
command. The arguments are all printed for review.

`make -j 3 my-awesome-packer-templates` spawns 3 packer processes, each of which
will bind to their own SSH port as determined by each process. This will also
work with WinRM, just change the port forward in `qemuargs` to map to WinRM's
default port of `5985` or whatever value you have the service set to listen on.
