The kernel runs as a firmware in the VTL mode, and the only way to restart in the VTL mode on x86 is to triple fault. Thus, one has to always supply "reboot=t" on the kernel command line in the VTL mode, and missing that renders rebooting not working. Define the machine restart callback to always use the triple fault to provide the robust configuration by default.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
