Re: Invalid accelerator kvm / error: kvm run failed Function not implemented ERRORS trying to virtualize a guest OS on the ARM Chromebook running with a relatively recent kernel version and KVM enabled

[Mario Marietto]

I think to be close,but it still does not work.These are the parameters that I used :

/mnt/./monta-fisso

sleep 2
qemu-system-arm \
    -enable-kvm -serial stdio \
    -m 512 -M virt -cpu cortex-a15 \
    -drive file=/mnt/fisso/OS/FreeBSD/FreeBSD-13.2.qcow2,id=virtio-blk,if=none \
    -device virtio-blk,drive=virtio-blk \
    -device virtio-net,netdev=net0,mac="52:54:00:12:34:55" \
    -netdev type=user,id=net0 \

    -drive if=pflash,format=raw,file=/usr/share/AAVMF/AAVMF32_CODE.fd \

unfortunately :

where could be the error ?

Try "-pflash *.fd" or "-drive if=pflash,format=raw,file=*.fd", if it works for Arm machines. 

 

I saw that OVMF developers didn't recommend to use "-bios" because image will be mounted as ROM and will not be able to save bios settings. 

 

With best regards,

I've found the right uefi file to use :

/usr/share/AAVMF/AAVMF32_CODE.fd

so now every piece is on the right place (I hope) :

qemu-system-arm \
    -enable-kvm -serial stdio \
    -m 512 -M virt -cpu cortex-a15 \
    -drive file=/mnt/fisso/OS/FreeBSD/FreeBSD-13.2.qcow2,id=virtio-blk,if=none \
    -device virtio-blk,drive=virtio-blk \
    -device virtio-net,netdev=net0,mac="52:54:00:12:34:55" \
    -smbios type=2 -nodefaults \
    -netdev type=user,id=net0 \
    -bios "/usr/share/AAVMF/AAVMF32_CODE.fd"
    -append "earlyprintk=ttyAMA0 console=ttyAMA0 mem=512M \
             virtio_mmio.device=1M@0x4e000000:74:0 \
             virtio_mmio.device=1M@0x4e100000:75:1 \
             root=/dev/vda rw ip=dhcp --no-log"

Does anyone still see some mistakes ?

I remember. So,more or less,it should be something like this :

qemu-system-arm \
    -enable-kvm -serial stdio \
    -m 512 -M virt -cpu cortex-a15 \
    -drive file=/mnt/fisso/OS/FreeBSD/FreeBSD-13.2.qcow2,id=virtio-blk,if=none \

    -smbios type=2 -nodefaults \
    -netdev type=user,id=net0 \
    -bios "OVMF_CODE.fd"
    -append "earlyprintk=ttyAMA0 console=ttyAMA0 mem=512M \
             virtio_mmio.device=1M@0x4e000000:74:0 \
             virtio_mmio.device=1M@0x4e100000:75:1 \
             root=/dev/vda rw ip=dhcp --no-log"

The problem is that devuan does not offer the proper OVMF file,as you can see :

# apt search ovmf

Sorting... Done
Full Text Search... Done

ovmf/stable 2020.11-2+deb11u1 all
  UEFI firmware for 64-bit x86 virtual machines

ovmf-ia32/stable 2020.11-2+deb11u1 all
  UEFI firmware for 32-bit x86 virtual machines

These UEFI files are for x86-64 bit,so they are not good for armhf. Where I can find the right ones ?

Try "-kernel kernel.img -initrd initrd.img". 

Oh, too late. :) 

 

By the way, I myself didn't experiment much with qemu-system-arm, but people successfully ran hdd/iso images with EFI bioses (for Arm architecture), if I'm not mistaken. 

 

With regards.
