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

--- a/hypervisor/arch/x86/Kconfig

+++ b/hypervisor/arch/x86/Kconfig

@@ -1,6 +1,6 @@

choice

        prompt "ACRN Scenario"

-       default SDC

+       default INDUSTRY

        help

          Select the scenario name to load corresponding VM configuration.

 

Then;

 

cd ~/acrn-hypervisor

make

sudo make install

 

And try again.

 

Thanks!

 

BR.

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

cpu1 online=1

cpu2 online=1

cpu3 online=1

pm by vuart node-index = 1

SW_LOAD: get ovmf path /usr/share/acrn/bios/OVMF.fd, size 0x200000

vm_create: hard_rtvm

VHM api version 1.0

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
