now UP2 board use ttyS1 as debug uart in HV, and vuart ttyS0 in SOS kernel (acrn.conf default configure), its default IRQ is 4, but SOS kernel will also assign IRQ4 to its ttyS1, they're sharing one IRQ, and it can cause SOS boot hung issue, for HV not support sharing IRQ now. some boards use ttyS0 as debug uart, it has not this issue; for that board, SOS will assign IRQ5 to its ttyS1, no sharing IRQ. change it to IRQ6 to avoid the issue.

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/
