	// VMware machines, Packer will output VNC connection information in case you
	// need to connect to the console to debug the build process.
	// Some users have experienced issues where Packer cannot properly connect
	// to a VM if it is headless; this appears to be a result of not ever having
	// launched the VMWare GUI and accepting the evaluation license, or
	// supplying a real license. If you experience this, launching VMWare and
	// accepting the license should resolve your problem.

	// The minimum and maximum port
	// to use for VNC access to the virtual machine. The builder uses VNC to type
	// the initial boot_command. Because Packer generally runs in parallel,
	// Packer uses a randomly chosen port in this range that appears available. By
	// default this is 5900 to 6000. The minimum and maximum ports are
	// inclusive.
