Hi Alfonso,
You are not building with CONFIG_RELEASE=y by any chance? (If the tag info below is correct, the default is not to use that). In case you did, note that it will disable the
use of the serial port.
Based on the output I see, it should work though with the default settings. Are you seeing any output at all on the serial port (e.g. Bios output)? Make sure to use these
settings in minicom (or whatever else you use): 115200 8N1, both HW and SW flow control should turned off (this last one often gets me, the default may be that one is on).
As far as I know, the HVlog error shouldn’t affect the functionality, so there is something else going wrong in your set-up. Let me continue dig through the logs and see if
I can spot some other useful info.

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:
$ acrn-dm -v
DM version is: 1.4-unstable-bcefd673 (daily tag:acrn-2019w47.1-140000p), build by ubuntu@2020-01-09 09:45:17

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 Alfonso
Could you please share acrn.efi and acrn-dm commit info?
With following steps:
-
run “acrn-dm -v” in sos
-
run “version” in HV console
We need them to reproduce this issue.
Thanks!
BR.

Hi Alfonso,
You are using default launch_hard_rt_vm.sh, right?
Maybe, it is SDC(by default) scenario for your acrn.efi,
Please refer following patch:
diff --git a/hypervisor/arch/x86/Kconfig b/hypervisor/arch/x86/Kconfig
index 41a78fe7..386a074b 100644

help
Select the scenario name to load corresponding VM configuration.
Then;
cd ~/acrn-hypervisor
make
sudo make install
And try again.
I tried with that, but no difference in the traces :-/.
Actually I had already tried with 'make all BOARD=nuc7i7dnb SCENARIO=industry', which I guess i the same.

Subject: [acrn-users] Cannot launch hart RT UOS when running Ubuntu as SOS
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. 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 and things fail:
$ sudo /usr/share/acrn/samples/nuc/launch_hard_rt_vm.sh
pm by vuart node-index = 1
SW_LOAD: get ovmf path /usr/share/acrn/bios/OVMF.fd, size 0x200000
failed to create VM hard_rtvm
The kernel output is:

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!
Alfonso
