For guest reset, if the highest severity guest reset will reset system. There is vm flag to call out the highest severity guest in specific scenario which is a static guest severity assignment. There is case that the static highest severity guest is shutdown and the highest severity guest should be transfer to other guest. For example, in ISD scenario, if RTVM (static highest severity guest) is shutdown, SOS should be highest severity guest instead. The is_highest_severity_vm() is updated to detect highest severity guest dynamically. And promote the highest severity guest reset to system reset. Also remove the GUEST_FLAG_HIGHEST_SEVERITY definition. Tracked-On: #4270 Signed-off-by: Yin Fengwei <fengwei.yin@intel.com>
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/
