QNX / Page-Fault question
I'm completely new to ACRN (only having learned about it yesterday). Let me know if this is not the proper group to post this question to.
Should ACRN support any OS or does the OS require explicit support in order to work with ACRN? Or similarly, does ACRN require specific support for certain OSes?
As an example, should I be able to run QNX on the ACRN hypervisor, or would it/ACRN need some sort of support built-in?
I'm basing my experiment on the information from the following pages and trying to apply it to boot QNX:
I have an EFI file named QNX.efi that I can boot on a NUC7i3DNB when booting on bare metal just fine. However when I try to boot this on the ACRN hypervisor I get a page fault error (which I'll copy below).
My launch file is based on the launch_vxworks.sh file but has a few changes, including the following for acrn-dm parameters. Is there anything obviously wrong with it?
-m $mem_size \
-c $2 \
-s 0:0,hostbridge \
-s 1:0,lpc \
-s 2,pci-gvt \
-G "10 128 6" \
-l com1,stdio \
-s 5,virtio-console,@pty:pty_port \
-s 6,virtio-hyper_dmabuf \
-s 3,virtio-blk,./qnx.img \
--virtio_poll 1000000 \
--ovmf ./OVMF.fd \
I can change the QNX.efi to a shell.efi, as an sanity check, and the EFI shell boots up just fine. If I try to launch the QNX.efi from within the EFI shell then I get the same page fault error.
The error that I'm getting is copied below. Where would this error be coming from? Would it be OVMF.fd, the ACRN hypervisor, or something else (like the QNX bootloader)?

!!!! Can't find image information. !!!!
Any help/advice would be appreciated. Is what I'm attempting reasonable or should I not expect an OS like QNX to run on the ACRN hypervisor?
As a side question, are there build instructions for the ACRN fork of edk2 (https://github.com/projectacrn/acrn-edk2)? When I try building it I end up with an OVMF.fd file that's exactly the same size as when I build the regular edk2, which seems unlikely so I imagine that I'm doing something wrong. I found the following build instructions for edk2 (I'm using Ubuntu to build it): https://wiki.ubuntu.com/UEFI/EDK2. Would those instructions need any changes to build OVMF.fd from acrn-edk2?
