SMX should be disabled on guests. Actually current code assumes SMX is disabled (no VM exit handler for GETSEC and bit 2 of IA32_FEATURE_CONTROL is set), and this patch simply explicitly clear guest CPUID.01H.ECX[6]. Since both CPUID.01H.ECX[5] and CPUID.01H.ECX[6] are cleared from guest CPUID, MSR IA32_SMM_MONITOR_CTL is not available in guests. Need to make sure CR4.SMXE is cleared in guests.

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. .. _`Project ACRN`: https://projectacrn.org .. _`ACRN Hypervisor`: https://github.com/projectacrn/acrn-hypervisor .. _`Project ACRN documentation`: https://projectacrn.github.io/
