Paid ACRN developer research opportunity
[The ACRN mailing list admin has approved this message, posted by an ACRN maintainer.]
I'm looking to do paid interviews with embedded developers and system integration engineers who have completed one or more projects on ACRN, so we can learn about hypervisor usage. My name is Greg Labavitch, and I work at a user-centered research and design company (concreteux.com) that does research with technology professionals to provide input on the usefulness and usability of technical products and tools. I’m asking for one hour of your time for a remote video conference in the first half of March 2021, and we'll give you $150 for your participation. Your input will directly help the ACRN team understand your usage and development experience with ACRN. If you're interested, please fill out this Google Form questionnaire. For questions, please feel free to contact me at greg.labavitch@.... Thank you!

Re: Running ACRN in Virtualbox on NUC7i7DNH?
Hi Lonnie,
I have never heard of anyone attempting to boot ACRN in a VirtualBox VM… do let us know if you and have any success there! 😉
One other path you could take is to QEMU on Windows and follow this tutorial: https://projectacrn.github.io/latest/tutorials/acrn_on_qemu.html. I don’t have any experience with QEMU on Windows, but assuming it only does the emulation piece, you’d probably also want to use the HAXM driver to expose VT-x (https://github.com/intel/haxm).
Unfortunately, I don’t have any Windows machine other than my official IT machine… and I don’t think my IT department would be too thrilled if I was to try this on it 😊
Cheers, Geoffroy

Hi All,
I am running my new NUC7i7DNHE that has Windows 10 on it and have installed VirtualBox so that I can use it as a build platform for ACRN in some VM's.
I am wondering if anyone has been able to install and boot up ACRN in a VirtualBox VM with Clear Linux or other?
I have been using these dated ACRN videos as guides while trying to replicate just a basic install and boot up of ACRN to see it in action before wiping my NUC and working from that pathway.
--- ACRN Getting Started and Demo
--- Info on ACRN design
Basically, I would just like to see it run locally, in a VM if possible, before digging heavier into it.
Cheers, Lonnie

Re: Can't enable uart for Ubuntu SOS

Hi zhangshuai

Could you please try "make install" instead of copy the grubx64.efi? It works for my setup: root@acrn-OptiPlex-9010:/home/acrn/work/grub-2.04# make install root@acrn-OptiPlex-9010:/home/acrn/work/grub-2.04# grub-install -V grub-install (GRUB) 2.02-2ubuntu8.17 root@acrn-OptiPlex-9010:/home/acrn/work/grub-2.04# reboot root@acrn-OptiPlex-9010:/home/acrn# grub-install -V grub-install (GRUB) 2.04 BR.

hi Shuai,

If you follows https://projectacrn.github.io/latest/tutorials/using_grub.html?#installing-self-built-grub then you should not replace grubx64.efi to /boot/efi/EFI/ubuntu since grub-mkimge -p parameter is incorrect. Ubuntu GRUB is built with its own build script and parameters. please put efi application to your "-p" specified folder, (maybe you can try "grub-mkimage -p /EFI/grub ..." to replace your Ubuntu grub efi but I am not sure it can work, depends on your ubuntu version.)

Re: Can't enable uart for Ubuntu SOS
Hi Zhangshuai,
toggle quoted messageShow quoted text
What is your version of Ubuntu? I'm running Ubuntu 20.04 on a machine and did not have to update Grub to install ACRN. This is the right location, do you see the Grub menu at all after updating the Grub binary? If not, can you get to the EFI shell and manually start it from there? Make sure you have secure boot turned off in your bios as well. Back to your question about the UART, can you also try to use the bdf info instead, i.e.: # lspci | grep UART 00:18.0 . Series HSUART Controller #1 (rev 0b) 00:18.1 . Series HSUART Controller #2 (rev 0b) Which translates into uart=bdf@00:18.1 (if you want to use the second one for example). One last thing, make sure you have flow control (HW and SW) turned off in your serial port program (e.g. minicom). Geoffroy

Hi Shuai, First of all, make sure your grub has below commit: http://git.savannah.gnu.org/cgit/grub.git/commit/?id=0f3f5b7c13fa9b677a64cf11f20eca0f850a2b20 multiboot2: Set min address for mbi allocation to 0x1000

Can't enable uart for Ubuntu SOS
zhangshuai
Hello,
We have a development board with i5-7300U and tried to install acrn sos. We generated the board and scenario xmls using ACRN Configuration Tool, builded the acrn Hypervisor with RELEASE=0. When boot into ubuntu-service-vm, the system got stuck with HDMI show "loading ACRN..." There is a serial port on the board, so we want to output the boot log. The setting of the uart is as fellows. The serial works ok when boot into the Ubuntu without acrn kernel(native boot?) ; but there is nothing output when boot into ubuntu-service-vm. Is this configuration correct? or should I do something else? $ dmesg | grep tty [ 13.399735] dw-apb-uart.2: ttyS4 at MMIO 0xb151b000 (irq = 20, base_baud = 115200) is a 16550A [ 13.399769] printk: console [ttyS4] enabled $ vi /etc/grub.d/40_custom #!/bin/sh exec tail -n +3 $0 # This file provides an easy way to add custom menu entries.

Jacky, I assume the different content for the various screens will be coming from different VMs, is that correct? Do you have a need for 3D acceleration or can a remote display solution (e.g. VNC) meet your needs too? Thanks, Geoffroy

Wow, I boot acrn hypervisor and kernel successfully after enable vt-d in bios. Thank you very much, Geoffroy.

Re: How to run acrn on my Intel PC?
I believe it is. Can you confirm you have VT-d enabled in your bios? My understanding is that the DMAR table is set-up by the firmware if VT-d is enabled. If it does not do so, that is the sign of a broken firmware, and the next best source of action would be to contact the bios vendor. But let’s first make sure that VT-d is enabled in the bios.

The dmesg output is in the attached file.
I can't generate an XML file of my board, because /sys/firmware/acpi/tables/DMAR is missing in my system:
jacky@acrn:~/acrn-work/acrn-hypervisor/misc/acrn-config/target$ sudo python3 board_parser.py my-board
Is this information essential?
