Hi Liu and Geoffroy,

Right, I had forgotten to copy acrn.efi to the EFI partition after
re-compiling, thanks for reminding me. With that things move forward a
bit, but I still get errors:

It's related with iasl in your SOS. We have constrain for iasl version.

Do you know which version Alfonso should use? I believe it is 20191018 but it would be appreciated if you could confirm.

@Alfonso, if true, you can install it as follows
$ sudo apt update
$ sudo apt install m4 bison flex zlib1g-dev
$ cd ~
$ wget https://acpica.org/sites/acpica/files/acpica-unix-20191018.tar.gz
$ tar zxvf acpica-unix-20191018.tar.gz
$ cd acpica-unix-20191018
$ make clean && make iasl
$ sudo cp ./generate/unix/bin/iasl /usr/sbin/

Thanks,
Geoffroy

I have not been able yet to get output from the serial port, unfortunately.

I see there an hvlog error which I do not know if it is relevant or not:

Hi,

I have set-up Ubuntu as service OS by following the instructions
in
https://projectacrn.github.io/latest/tutorials/using_ubuntu_as_sos.html.

<https://projectacrn.github.io/latest/tutorials/using_ubuntu_as_sos.html>ACRN

is recognized as hypervisor and all looks good in principle.
However, after that I followed the instructions on how to start
an RT UOS
<https://projectacrn.github.io/latest/getting-

started/rt_industry.html#install-and-launch-the-preempt-rt-vm>

and things fail:____

$ sudo /usr/share/acrn/samples/nuc/launch_hard_rt_vm.sh____

cpu2 online=1____

cpu3 online=1____

pm by vuart node-index = 1____

Any hint on what might be going wrong and instructions on how to
debug? I followed previously the tutorial for Clear Linux and
was able to launch the RT image. I am using a NUC7i7DNH device.

Thanks!
