Re: launch_ubuntu in Ubuntu Service VM will automatically reboot

Jianjie Lin

Hi Terry,


Thank you for your reply.

My system is stable and “dmesg |grep ACRN” also shows the correct message.

After I launch the guest Ubuntu in the acrn kernel, the acrn kernel (service VM) is directly reboot, and nothing happens (Here means the system just restart, and go the service VM again, but guest VM did not launch)


I follow the instruction in to install the ACRN hypervisor,

and follow the tutorial in for installing the User VM, but without installing ROS environment.


Therefore the is almost the same as in the


By the way,  I try the ACRN hypervisor in a dell pc with x86 cpu, I am not sure if this the NUC platform or not? Or Can we use an PC for deploying the ACRN hypervisor?


Thank you very much again for your help, and support.

Hi Jianjie, welcome to ACRN world : )
For your reboot issue, first, you already successfully boot ACRN and Ubuntu SOS right, you can check dmesg as below. If you don't launch Guest VM, the system is stable right.

$ dmesg | grep ACRN
[    0.000000] Hypervisor detected: ACRN
[    0.862942] ACRN HVLog: acrn_hvlog_init

Then, you just run to launch guest VM, could you login Ubuntu for first time or just reboot and never succeed ? BTW, which platform are you trying on, a NUC platform, e.g., NUC11 ?

There are two steps for next debug: 1. could you enclosed your '', we can check if anything missed. 2. enable serial port to get HV log for next analysis:

Best & Regards
