ACRN Service VM Setup
*********************
You may refer to the steps in :ref:`kbl-nuc-sdc` for the
Intel NUC in order to set up ACRN on the KBL NUC. After following the steps in that guide,
you should be able to launch the Service VM successfully.
Setup for Using Windows as Guest VM
***********************************
All the patches to support WaaG have been upstreamed; you can download them
from the acrn-hypervisor repository.
Build ACRN EFI Images
=====================
#. Follow the steps described at :ref:`getting-started-building` to set up the build environment.
#. Use the ``make`` command to compile the ``acrn.efi`` and ``acrn-dm``::
$ git clone https://github.com/projectacrn/acrn-hypervisor.git
$ cd acrn-hypervisor
$ make FIRMWARE=uefi BOARD=kbl-nuc-i7
#. Get the outputs from::
$ build/hypervisor/acrn.efi
$ build/devicemodel/acrn-dm
#. Replace the ``acrn.efi`` and ``acrn-dm`` on your NUC:
a. Log in to the ACRN Service VM and then ``mount`` the EFI partition to ``/boot``
#. ``scp`` the ``acrn.efi`` and ``acrn-dm`` from your host::
# scp <acrn.efi from your host> /boot/EFI/acrn/
# scp <acrn-dm from your host> /usr/bin/
# chmod +x /usr/bin/acrn-dm && sync
Build Service VM Kernel
=======================
#. Follow the steps described at :ref:`getting-started-building` to set up the build environment.
#. Follow the steps below to build the ACRN kernel::
$ WORKDIR=`pwd`;
$ JOBS=`nproc`
$ git clone -b master https://github.com/projectacrn/acrn-kernel.git
$ cd acrn-kernel && mkdir -p ${WORKDIR}/{build,build-rootfs}
$ cp kernel_config_uefi_sos ${WORKDIR}/build/.config
$ make olddefconfig O=${WORKDIR}/build && make -j${JOBS} O=${WORKDIR}/build
$ make modules_install INSTALL_MOD_PATH=${WORKDIR}/build-rootfs O=${WORKDIR}/build -j${JOBS}
Update Kernel on KBL NUC
========================
#. Copy the new kernel image (bzImage) and its modules to the target machine::
# scp <your host>:$WORKDIR/build/arch/x86/boot/bzImage /boot/bzImage
# scp -r <your host>:$WORKDIR/build-rootfs/lib/modules/* /lib/modules/
# cp /boot/loader/entries/acrn.conf /boot/loader/entries/acrngt.conf
#. Modify ``acrngt.conf`` to the content as given below:
.. code-block:: none
title The ACRNGT Service VM
linux /bzImage
options console=tty0 console=ttyS0 root=/dev/sda3 rw rootwait ignore_loglevel no_timer_check consoleblank=0 i915.nuclear_pageflip=1 i915.avail_planes_per_pipe=0x010101 i915.domain_plane_owners=0x011100001111 i915.enable_gvt=1 i915.enable_conformance_check=0 i915.enable_guc=0 hvlog=2M@0x1FE00000
.. note:: Change ``/dev/sda3`` to your file system partition.
#. ``reboot`` the Service VM and select ``The ACRNGT Service VM`` from the boot menu to apply
the ACRN kernel and hypervisor updates.
Create Windows 10 Image
=======================
Create a Windows 10 image which includes two steps:
#. Re-generate an ISO that includes winvirtio or virtio-win drivers and the Windows graphics drivers that were pre-installed
from the original Windows ISO.
#. Install Windows 10 onto the virtual disk.
Preparations
------------
* Download `Windows 10 ADK <https://docs.microsoft.com/en-us/windows-hardware/get-started/adk-install>`_
according to your working Windows 10 version.

and click ``Install`` to continue the installation.
.. note:: You need to install Windows 10 ADK only once.
Pre-install drivers and re-generate Windows ISO
-----------------------------------------------
#. Create a folder on the ``C:`` drive called ``WIM``, so you have a folder ``C:\WIM``
#. Create a folder on the ``C:`` drive called ``Mount``, so you have a folder ``C:\Mount``
#. Right click the downloaded ``virtio-win-0.1.141.iso`` and select ``Mount``. The ISO will be mounted to a drive;
for example, drive ``D:``
Or used Oracle Driver
Right click the downloaded ``winvirtio.iso`` and select ``Mount``. The ISO will be mounted to a drive;
for example, drive ``D:``
#. Use ``7-zip`` or similar utility to unzip the downloaded Windows graphics driver
``igfx_win10_100.7212.zip`` to a folder,
for example, to ``C:\Dev\Temp\wim\igfx_win10_100.7212``
#. Right click the downloaded Windows ISO, for example, ``windows10-17763-107-LTSC.iso``, select ``Mount``,
the ISO will be mounted to a drive; for example, drive ``E:``
#. Copy ``E:\sources\boot.wim`` and ``E:\sources\install.wim`` to ``C:\WIM``
#. Depending on your Windows ISO image, more than one image may be included in the ``WIM``.
Run ``dism /get-wiminfo /wimfile:C:\WIM\install.wim`` with administrator privileges.
Select the ``Index`` you want. For ``windows10-17763-107-LTSC.iso``,
there is only one ``Index``; it is ``1``
.. figure:: images/install_wim_index.png
:align: center
#. Create a batch file named ``virtio-inject-boot.bat`` [1]_ to modify
``boot.wim`` to inject drivers (using the mounted Windows ISO drive
(``D:``), image Index (``1``), and folder where the unzipped Windows
graphics drivers were placed, from the previous steps (update this
batch file as needed)::

Run this script in a command prompt running as administrator. It may also
take 4-5 minutes to run, depending on your Windows system performance.
#. After running these two scripts the files ``C:\WIM\boot.wim`` and ``C:\WIM\install.wim``
will be updated to install these drivers into the image:
- Virtio-balloon
- Virtio-net
- Virtio-rng
- Virtio-scsi
- Virtio-serial
- Virtio-block
- Virtio-input
- Windows graphics drivers
#. Use 7-zip to unzip the downloaded Windows ISO to a folder; for example, into
``C:\Dev\Temp\wim\windows10-17763-107-LTSC``
#. Delete ``C:\Dev\Temp\wim\windows10-17763-107-LTSC\sources\boot.wim`` and
``C:\Dev\Temp\wim\windows10-17763-107-LTSC\sources\install.wim``
#. Copy ``C:\WIM\boot.wim`` and ``C:\WIM\install.wim`` to ``C:\Dev\Temp\wim\windows10-17763-107-LTSC\sources``
#. Download and unzip `cdrtools-3.01.a23-bootcd.ru-mkisofs.7z
<http://reboot.pro/index.php?app=core&module=attach&section=attach&attach_id=15214>`_ to a folder;
for example, to ``C:\Dev\Temp\wim\cdrtools-3.01.a23-bootcd.ru-mkisofs``
#. Create a batch file named ``mkisofs_both_legacy_and_uefi.bat``
containing (update folder names as needed to reflect where the
referenced files are located on your system, and ``inputdir``,
``outputiso`` and ``mkisofs.exe`` path, downloaded by the previous
step)::
set inputdir=C:\Dev\Temp\wim\windows10-17763-107-LTSC
set outputiso=C:\Dev\Temp\wim\mkisofs_iso\windows10-17763-107-LTSC-Virtio-Gfx.iso
set label="WIN10_17763_107_LTSC_VIRTIO_GFX"
set biosboot=boot/etfsboot.com
set efiboot=efi/microsoft/boot/efisys.bin
C:\Dev\Temp\wim\cdrtools-3.01.a23-bootcd.ru-mkisofs\mingw\mkisofs.exe \
-iso-level 4 -l -R -UDF -D -volid %label% -b %biosboot% -no-emul-boot \
-boot-load-size 8 -hide boot.catalog -eltorito-alt-boot \
-eltorito-platform efi -no-emul-boot -b %efiboot% -o %outputiso% \
%inputdir%
Run this ``mkisofs_both_legacy_and_uefi.bat`` script. The resulting
ISO will be generated in ``outputiso`` location you specified.
Create Raw Disk
---------------
Run these commands on the Service VM::
# swupd bundle-add kvm-host
# mkdir /root/img
# cd /root/img
# qemu-img create -f raw win10-ltsc-virtio.img 30G
Install Windows 10
------------------
.. note:: Make sure you have configured your monitor and display according to **3** of
:ref:`Boot Windows with GVT-g on ACRN <waag_display_conf_lable>`.
#. Copy ``/usr/share/acrn/samples/nuc/launch_win.sh`` to ``install_win.sh``::
# cp /usr/share/acrn/samples/nuc/launch_win.sh ~/install_win.sh
#. Add the following lines **before** the ``acrn-dm`` command line in ``install_win.sh``. It is used
to passthrough USB to WaaG, by which both mouse and keyboard can be used during the Windows installation::
echo "8086 9d2f" > /sys/bus/pci/drivers/pci-stub/new_id
echo "0000:00:14.0" > /sys/bus/pci/devices/0000:00:14.0/driver/unbind
echo "0000:00:14.0" > /sys/bus/pci/drivers/pci-stub/bind
.. note:: You may need to change the bdf and vid/pid of the USB controller in the above command to match those
of your platform. Use ``lspci`` and ``lspci -n`` to get this information.
#. Edit the ``acrn-dm`` command line in ``install_win.sh`` as follows:
- Change ``-s 3,virtio-blk,./win10-ltsc-virtio.img`` to your path to the Windows 10 image.
- Add ``-s 6,passthru,0/14/0``.
.. note:: You may need to change 0/14/0 to match bdf of the USB controller of your platform.
- Add ``-s 8,ahci,cd:./windows10-17763-107-LTSC-Virtio-Gfx.iso`` to point to the ISO you re-generated above.
- Add ``-s 9,ahci,cd:./virtio-win-0.1.141.iso`` to point to your path to the virtio-win iso.
Or if you used the Oracle driver:
- Add ``-s 9,ahci,cd:./winvirtio.iso`` to point to your path to the winvirtio iso.
#. Run ``install_win.sh``.
#. When the display reads "Press any key to boot from CD or DVD" on the monitor, press any key in the terminal on the
**Host** side.

Boot Windows with GVT-g on ACRN
===============================
#. Modify the ``/usr/share/acrn/samples/nuc/launch_win.sh`` script to specify the Windows image generated above.
#. Run the ``launch_win.sh`` and you should see the WaaG desktop coming up over the HDMI monitor (instead of the VNC).
.. note:: Use the following command to disable the GNOME Display Manager (GDM) if it is enabled::
# sudo systemctl mask gdm.service
.. note:: You must connect two monitors to the KBL NUC in order to launch Windows with
the default configurations above.
.. note:: The second monitor must include the Weston desktop. If you have set up Weston in the Service VM,
follow the steps in :ref:`skl-nuc-gpu-passthrough` to set up Weston as
the desktop environment in Service VM in order to experience Windows with the AcrnGT local display feature.
