SDM mentioned: "If either the “unrestricted guest†VM-execution control or the “mode-based execute control for EPT†VM- execution control is 1, the “enable EPT†VM-execution control must also be 1." However, we can still observe unrestricted_guest is Y after inserting the kvm-intel.ko w/ ept=N. It depends on later starts a guest in order that the function vmx_compute_secondary_exec_control() can be executed, then both the module parameter and exec control fields will be amended. This patch fixes it by amending module parameter immediately during vmcs data setup.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
