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'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 ?
