Guest MSR_IA32_MISC_ENABLE read simply returns the value set by guest. Guest MSR_IA32_MISC_ENABLE write: - Clear EFER.NXE if MSR_IA32_MISC_ENABLE_XD_DISABLE set. - MSR_IA32_MISC_ENABLE_MONITOR_ENA: Allow guest to control this feature when HV doesn't use this feature and hw has no bug. vcpuid update according to the change of the msr will be covered in following patch.

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/
