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]

These are the config parameters if the hardware is x86_64 :


./configure --target-list=x86_64-softmmu --enable-opengl --enable-gtk --enable-kvm --enable-guest-agent --enable-spice --audio-drv-list="oss pa" --enable-libusb

I don't know if those parameters are valid even for armhf.

ok thanks. Are the following parameters correct still today ? something is missing ? thanks.

a) to compile qemu :

./configure \
     --target-list=arm-softmmu \
     --audio-drv-list=alsa,pa \
     --enable-fdt --enable-kvm --enable-sdl

b) to run a guest os (I want to virtualize FreeBSD)


qemu-system-arm \
    -enable-kvm -serial stdio -kernel (here I think that I should put the FreeBSD kernel,but I'm not sure at all,I should ask) \
    -m 512 -M virt -cpu cortex-a15 \
    -drive file=ubuntu.img,id=virtio-blk,if=none \
    -device virtio-blk,drive=virtio-blk,transport=virtio-mmio.0 \
    -device virtio-net,transport=virtio-mmio.1,netdev=net0,mac="52:54:00:12:34:55" \
    -netdev type=user,id=net0 \
    -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"

I used -M virt,because you said that -M vexpress-a15 is not good. I hope that  -cpu cortex-a15 is good,anyway.

The source code archive [1] contains the code for all architectures.
 From that you configure your build environment, where you can specify
the target architecture.


Kind regards,

Paul
