Version 0.1 features include: Version 0.1 features include:
* ACRN hypervisor (Type 1 hypervisor) - Acrnctl
* A hybrid VMM architecture implementation - Acrntrace
* Multiple User OS supported - Acrnlog
* VM management - such as VM start/stop/pause, virtual CPU pause/resume - SOS lifecycle
* CPU virtualization - vSBL
* Memory virtualization - virtio-blk
* I/O emulation - virtio-net
* Virtual interrupt - USB pass-thru
* VT-x and VT-d support - CSE pass-thru
* Hypercall for guest - IOC sharing (incl. cbc attach, cbc driver)
* Device emulation - IPU pass-thru
* Device pass-through mechanism - BT pass-thru
* Device Emulation mechanism - SD card pass-thru
* Virtio console - audio pass-thru

Known Issues
============
* GPU - Preemption (Prioritized Rendering,
* Batch Preemption, QoS Rendering)
* Preemption feature works, but performance is not optimized yet.
* Wifi not supported in guest OS
* Audio pass-through to guest OS, but can only be validated on driver level
using command line or alsa-player, and only supports limited formats
* CSME pass-through to guest OS
* GVT-g is available, need to perform features after configured properly
* Camera works in Android guest. But camera app may crash after 5 mins
* SD card works in Android guest, but does not support hot-plug.
* Surface Sharing: Sometimes the window setup on Service OS takes up to 30 second
* Sometimes system hangs, especially when workload is high (e.g. running benchmarks, playing videos)
