Hello together,

a short introduction I'm a research assistant at Reutlingen University. I work with the LF projects zephyr and AGL. My universtiy will hopefully join the LF soon.  I'm working on getting AGL running on UP² with ACRN as hypervisor.  We plan to distribute our AGL builds to different boards at university and we want to do that with ACRN.

I followed the documentation on the latest version. I changed the things according the UP² getting started.

Everything worked until I tried to start the "acrn hypervisor" in grub then it hangs on

"fb: switching to inteldrmfb from EFI VGA"

Below I have my changed lines for Up²:

sudo mount /dev/mmcblk0p1 /mnt

sudo mkdir /mnt/EFI/acrn

sudo cp /usr/lib/acrn/acrn.efi /mnt/EFI/acrn/

efibootmgr -c -l "\EFI\acrn\acrn.efi" -d /dev/mmcblk0 -p 1 \

    -L "ACRN Hypervisor" \

    -u "bootloader=\EFI\org.clearlinux\bootloaderx64.efi uart=bdf@0:18.1 vuart=ttyS1@irq5"

sudo vi /mnt/loader/entries/acrn.conf

Thank you  and greetings

Hello Geoffrey,

thanks for your help. Since your replied I re installed the system a couple of times (min. 10x) because of errors.

The first thing is that I downloaded "clear-26200-installer" and the swupd verify not worked for 26200. I changed to version 29030 that was recommended.

The second wired thing was that after install of all packages the reboot sometimes not worked "Failed to talk to init daemon".

The next error was that I got errors belong to rcx  (lines 987,1056) in the make procdure of the acrn-hypervisor.

"arch/x86/guest/instr_emul.c: In function ‘emulate_instruction’:
arch/x86/guest/instr_emul.c:1056:7: error: ‘rcx’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
 1056 |   rcx = rcx - 1;
      |   ~~~~^~~~~~~~~
arch/x86/guest/instr_emul.c:987:11: note: ‘rcx’ was declared here
  987 |  uint64_t rcx, rdi, rsi, rflags;
      |           ^~~
"

That worked sometimes and sometimes not.

The last error that occurred was that I had no space for updating the "clr-boot-manager", I found out that I had too much bootoptions in the system. 

I'm stucking in getting the thing working.

I don't know if you could help me or if I destroyed my whole system.

Greetings

Thomas

Hi Thomas,

 

Welcome to the ACRN community!!

 

Your kernel command-line is most likely incorrect, change root=/dev/mmcblk0p1 to root=/dev/mmcblk0p3 (the first partition is typically the EFI System Partition (ESP), the root filesystem being put on the 3^rd partition in Clear Linux). Can you try to update it and let us know if that gets you further?

 

Thanks!
Geoffroy

Hi Can I install it into a laptop for evaluation purpose and later onto the NUC?
Please confirm whether hypervisor works on x86 laptop or not.

Thanks,
VJRao

We do not test it on standard laptop. The likekihood of success depends
amongst other things of the processor you have on the laptop. We test
ACRN on Apollo Lake and Kaby Lake processors. You also need the laptop
to have an EFI bootloader.

I guess you have seen the relevant pages in our documentation by now,
but if not, here is where you should start from:
- Getting Started Guide:
https://projectacrn.github.io/latest/getting-started/apl-nuc.html
- Supported HW: https://projectacrn.github.io/latest/hardware.html

Feel free to try and report out on this list if you're having problems
but be aware that we may not be able to easily troubleshoot this,
especially if you do not have a serial port connection to the laptop.

We should also shortly have another option for you to try out ACRN
without a NUC, that's via QEMU. It's not quite ready yet, you can track
progress here if you're interested in this option:
https://github.com/projectacrn/acrn-hypervisor/issues/3198

Thanks,
Geoffroy

Hi Geoffroy,

Thank you very. Much for quick resolution. My task to evaluate ACRN on clear OS. Hope I could complete this task with a NUC7 box.


BR,
VJRao.

Do you already have one of the NUC listed on the "Supported Hardware"
page?

It's great to hear you'll be evaluating ACRN and Clear Linux, please
let us know how you get on, even if you don't hit any issue ;-)

Thanks,
