Re: Questions about ACRN's dependency and Other Linux Distro Supports

Yang, Ailin

The normal boot flow is:

EFI BIOS-> acrn.efi->grub->SOS kernel -> user land

ACRN ubuntu SOS appeared in boot list” doesn’t mean the grub must be loaded by acrn.efi.

This is why I asked you to check #1 point to make sure you first boot stage is correct.


By the way, you need to change org.clearlinux.pk414-sos.4.14.74-115 to org.clearlinux.iot-lts2018-sos.4.19.0-19

We have update kernel to 4.19 already if you are using ACRN v0.3 or latest.

Hello, Yang.
Thank you for the reply.

1,  is your acrn.efi loaded by EFI firmware correctly?

     You can run “ sudo efibootmgr –v” to check if the “ACRN Hypervisor” is first boot option,

    Also you can enter the EFI firmware at boot (using F10) to select “ACRN Hypervisor”

  -> [TK] ACRN ubuntu SOS appeared in boot list, but after selecting it, my hardware didn't show anything and rebooted in few seconds. 

    because of that I couldn't go further step 2 or 3 as you mentioned. 

I was wondering if the SOS kernel that I'm using(org.clearlinux.pk414-sos.4.14.74-115) has device dependency (might be CPU, graphic card and so on)

I think knowing which component or options are dependent on device would be helpful to porting ACRN hypervisor and Service OS
