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

Yang, Ailin

Showing “Black screen” only is hard to know your issue exactly.

Also NUC6i5SYH is not official supported hardware,  we didn’t run test with it.


But can you check below 3 points to narrow down your issue first:

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”

2, check you SOS booted up successfully with right kernel and kernel command line?

You should able to login from remote ssh Client if the OS boot up successfully

3, check if ACRN hypervisor is running properly with “$ dmesg | grep ACRN”

     The right output is:

     $ dmesg | grep ACRN

   [    0.000000] Hypervisor detected: ACRN

   [    1.687128] ACRNTrace: acrn_trace_init, cpu_num 4

   [    1.693129] ACRN HVLog: acrn_hvlog_init

Hello. This is Taekyoung Kim. 
I have same problem with booting both Clear Linux SOS and Ubuntu SOS. 
My machine shows black screen and reboots automatically.

I have a question regarding this issue.
- Is there H/W dependency in the grub command? What are they? How can I get rid of dependency to boot SOS?

The environment I am using is below (Ubuntu as SOS)
H/W : NUC6i5SYH 
Hypervisor : ACRN Hypervisor v0.3
SOS Kernel : org.clearlinux.pk414-sos.4.14.74-115


menuentry 'ACRN ubuntu SOS' {


        insmod gzio

        insmod part_gpt

        insmod ext2

        linux  /boot/acrn/org.clearlinux.pk414-sos.4.14.74-115 pci_devices_ignore=(0:18:1)  console=tty0 console=ttyS0 i915.nuclear_pageflip=1 root=PARTUUID=b668057b-46ff-44fb-8ba0-624550abad2b rw rootwait ignore_loglevel no_timer_check consoleblank=0 i915.tsd_init=7 i915.tsd_delay=2000 i915.domain_plane_owners=0x011111110000 i915.enable_guc_loading=0 i915.enable_guc_submission=0 i915.enable_preemption=1 i915.context_priority_mode=2 i915.enable_gvt=1 hvlog=2M@0x1FE00000
