Shuo A Liu 8565750bbe hv: nested: Hide some capability bits from L1 guest 
* Hide 5 level EPT capability, let L1 guest stick to 4 level EPT.

 * Access/Dirty bits are not support currently, hide corresponding EPT
   capability bits.

 * "Mode-based execute control for EPT" is also not support well
   currently, hide its capability bit from MSR_IA32_VMX_PROCBASED_CTLS2.

ACRN Hypervisor
###############

The open source `Project ACRN`_ defines a device hypervisor reference stack and
an architecture for running multiple software subsystems, managed securely, on
a consolidated system by means of a virtual machine manager. It also defines a
reference framework implementation for virtual device emulation, called the
"ACRN Device Model".

The ACRN Hypervisor is a Type 1 reference hypervisor stack, running directly on
the bare-metal hardware, and is suitable for a variety of IoT and embedded
device solutions. The ACRN hypervisor addresses the gap that currently exists
between datacenter hypervisors, and hard partitioning hypervisors. The ACRN
hypervisor architecture partitions the system into different functional
domains, with carefully selected guest OS sharing optimizations for IoT and
embedded devices.

You can find out more about Project ACRN on the `Project ACRN documentation`_
website.
