Issue on latest Clear Linux and ACRN on UP2 board


Tomasz Bursztyka
 

Hi,

I cannot get ACRN hypervisor running on my setup:
- UPĀ² board (Celeron N3350)
- Clear Linux, fresh install, version 32910

I followed the documentation here:
- https://projectacrn.github.io/latest/tutorials/up2.html
- https://projectacrn.github.io/latest/tutorials/kbl-nuc-sdc.html


However, once I rebooted I did not get the kernel message
[ 0.000000] Hypervisor detected: ACRN

I only get these:
[ 5.759483] ACRNTrace: acrn_trace: not support acrn hypervisor!
[ 5.766132] ACRN HVLog: acrn_hvlog: not running under acrn
hypervisor!

So the hypervisor is not running.
There is no acrn related devices in /dev, I cannot start any VM
obviously etc..

Here is the kernel cmd line:

[ 0.000000] Command line: initrd=\EFI\org.clearlinux\freestanding-

The EFI configuration seems legit, however:

# efibootmgr -v
BootCurrent: 0003
Timeout: 1 seconds
BootOrder: 0003,0005,0001
Boot0001 UEFI: Built-in EFI Shell VenMedia(5023b95c-db26-429b-
a648-bd47664c8012)..BO
Boot0003* UEFI OS HD(1,GPT,f2d8aada-01a9-4c9c-86fe-
61ccb217e678,0x800,0x47000)/File(\EFI\BOOT\BOOTX64.EFI)..BO
Boot0005* ACRN Hypervisor HD(1,GPT,f2d8aada-01a9-4c9c-86fe-
61ccb217e678,0x800,0x47000)/File(\EFI\ACRN\ACRN.EFI)b.o.o.t.l.o.a.d.e.r
.=.\.E.F.I.\.o.r.g...c.l.e.a.r.l.i.n.u.x.\.b.o.o.t.l.o.a.d.e.r.x.6.4...
e.f.i. .u.a.r.t.=.b.d.f.@.0.:.1.8...1.


I switched the order to 0005,0003,0001 but it made no difference, and
once I did: the bootorder had automaticaly changed back to
0003,0005,0001. Is this nominal?

The acrn.efi is from acrn_quick_setup.sh, which requested to do:

cp /usr/lib/acrn/acrn.nuc7i7dnb.industry.efi /usr/lib/acrn/acrn.up-
apl01.industry.efi

So I did. (and installation seemed to go well.)


Any idea where the problem could be?
