Launch Configuration Options
|
|
##############################
|
|
|
|
As explained in :ref:`acrn_configuration_tool`, launch configuration files
|
|
define post-launched User VM settings. This document describes these option settings.
|
|
|
|
``user_vm``:
|
|
Specify the User VM ``id`` to the Service VM.
|
|
|
|
``user_vm_type``:
|
|
Specify the User VM type, such as ``CLEARLINUX``, ``ANDROID``, ``ALIOS``,
|
|
``PREEMPT-RT LINUX``, ``GENERIC LINUX``, ``WINDOWS``, ``YOCTO``, ``UBUNTU``,
|
|
``ZEPHYR`` or ``VXWORKS``.
|
|
|
|
``rtos_type``:
|
|
Specify the User VM Real-time capability: Soft RT, Hard RT, or none of them.
|
|
|
|
``mem_size``:
|
|
Specify the User VM memory size in megabytes.
|
|
|
|
``vbootloader``:
|
|
Virtual bootloader type; only supports OVMF.
|
|
|
|
``vuart0``:
|
|
Specify whether the Device Model emulates the vUART0 (vCOM1); refer to
|
|
:ref:`vuart_config` for details. If set to ``Enable``, the vUART0 is
|
|
emulated by the Device Model; if set to ``Disable``, the vUART0 is
|
|
emulated by the hypervisor if it is configured in the scenario XML.
|
|
|
|
``enable_ptm``:
|
|
Enable the Precision Timing Measurement (PTM) feature.
|
|
|
|
``usb_xhci``:
|
|
USB xHCI mediator configuration. Input format:
|
|
``bus#-port#[:bus#-port#: ...]``, e.g.: ``1-2:2-4``.
|
|
Refer to :ref:`usb_virtualization` for details.
|
|
|
|
``shm_regions``:
|
|
List of shared memory regions for inter-VM communication.
|
|
|
|
``shm_region`` (a child node of ``shm_regions``):
|
|
Configure the shared memory regions for the current VM, input format:
|
|
``[hv|dm]:/<shm name>,<shm size in MB>``. Refer to :ref:`ivshmem-hld`
|
|
for details.
|
|
|
|
``console_vuart``:
|
|
Enable a PCI-based console vUART. Refer to :ref:`vuart_config` for details.
|
|
|
|
``communication_vuarts``:
|
|
List of PCI-based communication vUARTs. Refer to :ref:`vuart_config` for
|
|
details.
|
|
|
|
``communication_vuart`` (a child node of ``communication_vuarts``):
|
|
Enable a PCI-based communication vUART with its ID. Refer to
|
|
:ref:`vuart_config` for details.
|
|
|
|
``passthrough_devices``:
|
|
Select the passthrough device from the PCI device list. We support:
|
|
``usb_xdci``, ``audio``, ``audio_codec``, ``ipu``, ``ipu_i2c``,
|
|
``cse``, ``wifi``, ``bluetooth``, ``sd_card``,
|
|
``ethernet``, ``sata``, and ``nvme``.
|
|
|
|
``network`` (a child node of ``virtio_devices``):
|
|
The virtio network device setting.
|
|
Input format: ``<device_name>[,vhost][,mac=<XX:XX:XX:XX:XX:XX>]``.
|
|
The ``<device_name>`` is the name of the TAP (or MacVTap) device.
|
|
It must include the keyword ``tap``. ``vhost`` specifies the
|
|
vhost backend; otherwise, the VBSU backend is used. The ``mac``
|
|
address is optional.
|
|
|
|
``block`` (a child node of ``virtio_devices``):
|
|
The virtio block device setting.
|
|
Input format: ``[blk partition:][img path]`` e.g.: ``/dev/sda3:./a/b.img``.
|
|
|
|
``console`` (a child node of ``virtio_devices``):
|
|
The virtio console device setting.
|
|
Input format:
|
|
``[@]stdio|tty|pty|sock:portname[=portpath][,[@]stdio|tty|pty:portname[=portpath]]``.
|
|
|
|
``cpu_affinity``:
|
|
A comma-separated list of Service VM vCPUs assigned to this VM. A Service VM vCPU is identified
|
|
by its lapic ID.
|
|
|
|
.. note::
|
|
|
|
The ``configurable`` and ``readonly`` attributes are used to mark
|
|
whether the item is configurable for users. When ``configurable="n"``
|
|
and ``readonly="y"``, the item is not configurable from the web
|
|
interface. When ``configurable="n"``, the item does not appear on the
|
|
interface.
