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 EPTâ€
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.
