As specified in Intel's SDM, do not allow the L1 hypervisor to launch an L2 guest with the VM-execution controls for "unrestricted guest" or "mode-based execute control for EPT" set and the VM-execution control for "enable EPT" clear. Note that the VM-execution control for "mode-based execute control for EPT" is not yet virtualized by kvm.

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.
