====== Virtualization Expert Group ======

The AGL Virtualization Expert Group (EG-VIRT) is responsible to design and implement virtualization solutions for AGL. This expert group has been created from a BoF held in the Munich AMM 2016 meeting (slides available [[http://events.linuxfoundation.org/sites/events/files/slides/vosys_AGLAMM16_2016_9_7_public.pdf|here]]).

Containers, Hypervisors (both based on Virtualization Extensions and TrustZone) and any other virtualization solution for x86/ARM are considered to be of interest for this Expert Group. Mainline AGL  support the KVM hypervisor on the Renesas RCar M3 platform).

Today the EG-VIRT expert group is focused on defining the Virtualization platform architecture of AGL. The result of the work of the EG-VIRT group in this direction is this [[https://www.automotivelinux.org/wp-content/uploads/sites/4/2018/06/agl_software_defined_car_jun18.pdf|white paper]].

====== Hypervisor and eCockpit requirements ======

Virtualization in the AGL Requirements: Eric Shufro, Satpreet Singh (Panasonic)

1. Vision
    *	Have an opensoruce project supporting a ecockpit out of the box solution.
    *	Support IVI (android/AGL), cluster (AGL), safe RTOS (AutoSAR, RTOS)

2. Hypervisor
    *	ability to virtualize GPU, IOs, networking, CPU and run different virtual machines.
    *	Support memory separation for each guest
    *	Support physical suspend to RAM.
    *	Inter VM communication (Shared memory, network, character)
    *	Meet ASIL Safety requirements

3. System Behavior
    *	Power management of vehicle micro and main micro
    *	Co-ordinate startup and shutdown of all VMs.
    *	Support early boot using suspend to ram or suspend to disk or other techniques
    *	Interprocessor communication (bootmicro and mainmicro for different systems (IVI, cluster) including safety considerations.

4. Goals
    *	Create standard interfaces for inter VM communication.
    *	Create vehicle power moding strategy and interfaces to VM.
    *	Create a system block architecture with recommended separation of concerns.
    *	Standard way of sharing hardware (Virtio)
    *	Standard way of software update including peripheral devices and delta update.
