Description
|
|
***********
|
|
|
|
The ``acrnctl`` tool helps users create, delete, launch, and stop a User
|
|
OS (UOS). The tool runs under the Service OS, and UOSs should be based
|
|
on ``acrn-dm``. The daemon for acrn-manager is `acrnd`_.
|
|
|
|
|
|
|
|
Usage
|
|
*****
|
|
|
|
You can see the available ``acrnctl`` commands by running:
|
|
|
|
.. code-block:: none
|
|
|
|
# acrnctl help
|
|
support:
|
|
list
|
|
start
|
|
stop
|
|
del
|
|
add
|
|
pause
|
|
continue
|
|
suspend
|
|
resume
|
|
reset
|
|
Use acrnctl [cmd] help for details
|
|
|
|
Here are some usage examples:
|
|
|
|
Add a VM
|
|
========
|
|
|
|
The ``add`` command lets you add a VM by specifying a
|
|
script that will launch a UOS, for example ``launch_UOS.sh``:
|
|
|
|
.. code-block:: none
|
|
|
|
# acrnctl add launch_UOS.sh -U 1
|
|
vm1-14:59:30 added
|
|
|
|
Note that the launch script must only launch one UOS instance.
|
|
The VM name is important. ``acrnctl`` searches VMs by their
|
|
names so duplicate VM names are not allowed. If the
|
|
launch script changes the VM name at launch time, ``acrnctl``
|
|
will not recognize it.
|
|
|
|
Delete VMs
|
|
==========
|
|
|
|
Use the ``delete`` command with a VM name to delete that VM:
|
|
|
|
.. code-block:: none
|
|
|
|
# acrnctl del vm1-14:59:30
|
|
|
|
List VMs
|
|
========
|
|
|
|
Use the ``list`` command to display VMs and their state:
|
|
|
|
.. code-block:: none
|
|
|
|
# acrnctl list
|
|
vm1-14:59:30 untracked
|
|
vm-yocto stopped
|
|
vm-android stopped
|
|
|
|
Start VM
|
|
========
|
|
|
|
If a VM is in a ``stopped`` state, you can start it with the ``start``
|
|
command:
|
|
|
|
.. code-block:: none
|
|
|
|
# acrnctl start vm-yocto
|
|
|
|
Stop VM
|
|
=======
|
|
|
|
Use the ``stop`` command to stop one or more running VM:
|
|
|
|
.. code-block:: none
|
|
|
|
# acrnctl stop vm-yocto vm1-14:59:30 vm-android
|
|
|
|
.. _acrnd:
|
|
|
|
acrnd
|
|
*****
|
|
|
|
The ``acrnd`` daemon process provides a way for launching or resuming a UOS
|
|
should the UOS shut down, either planned or unexpected. A UOS can ask ``acrnd``
|
|
to set up a timer to make sure the UOS is running, even if the SOS is
|
|
suspended or stopped.
|
|
The ``acrnd`` daemon stores pending UOS work to ``/usr/share/acrn/conf/timer_list``
|
|
and sets an RTC timer to wake up the SOS or bring the SOS back up again.
|
|
When ``acrnd`` daemon is restarted, it restores the previously saved timer
|
|
list and launches the UOSs at the right time.
|
|
|
|
A ``systemd`` service file (``acrnd.service``) is installed by default that will
|
|
start the ``acrnd`` daemon when the Service OS comes up.
|
|
You can restart/stop acrnd service using ``systemctl``
|
|
|
|
Build and Install
|
|
*****************
|
|
|
|
Source code for both ``acrnctl`` and ``acrnd`` is in the ``tools/acrn-manager`` folder.
|
|
Change to that folder and run:
|
|
|
|
.. code-block:: none
|
|
|
|
# make
|
|
# make install
