ok. Can you share the github address ? I found the source code for x86-x64 but not for armhf. On Fri, Aug 11, 2023 at 1:49 PM Peter Maydell wrote: > On Fri, 11 Aug 2023 at 12:19, Mario Marietto > wrote: > > Anyway,can you tell me where is the branch 5.1 for the qemu source code > for armhf ? >

ok. I will recompile a qemu version lower than 5.2. I've asked all around and someone says that I should use 5.1,someone else 4.9. Which version should I use ? And,please can you point me to a good tutorial that can teach me the procedure to recompile it ? I might find it by myself,but what I need

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 enable

I know. I've been working on this project since 1 year ago. But I'm stimulated by the "intellectual" challenge and even because old hardware should not be thrown away only because it is old. If it is still useful,it could be reused. The ARM chromebook in my opinion has been a nice toy to play

Hello, I tried to compile executable for Arm64 some time ago.  There is no special branch of QEMU for Arm hosts, you just need to find a toolchain to cross-compile for Arm.  Try to look at Linaro site, they have complete cross-configured GCC toolchains.  And then try script like this (note the

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)

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. On Fri, Aug

ok. I've been lucky. Qemu compiled successfully. Now I'm going to execute this command : qemu-system-arm \ -enable-kvm -serial stdio -kernel zImage \ -m 512 -M vexpress-a15 -cpu cortex-a15 \ -drive file=/mnt/fisso/bhyve/img/Linux/ubuntu2210.img,id=virtio-blk,if=none \ -device
