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 made some progress,but unfortunately I've got an error :

root@devuan:~/Desktop/qemu-v5.1.0# ./configure --target-list=arm-softmmu --enable-opengl --enable-gtk --enable-kvm --enable-guest-agent --enable-spice --audio-drv-list="oss pa" --enable-libusb

no errors here.

root@devuan:~/Desktop/qemu-v5.1.0# make

Specify a --target-list= option to configure unless you want to
sit around forever while it compiles every single supported
