Without it a PVH dom0 is mostly useless, as it would balloon down huge amounts of RAM in order get physical address space to map foreign memory and grants, ultimately leading to an out of memory situation. Such option is also needed for HVM or PVH driver domains, since they also require mapping grants into physical memory regions.

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 Restructured Text 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.
