Alpine qemu arm64 : no box available?


I’m new to vagrant and I’m trying to use qemu on macos to fire an alpine box, but the box seems unavailable :

vagrant box add generic/alpine318 --provider qemu

answers The box you attempted to add doesn't match the provider you specified.

Neither automatic download (no --provider) nor when downloading manually the box (, adding failed because it seems to be only packaged for libvirt.

Despite this JSON descriptor(ht tps:// seems to show a box :

Does this box only available with libvirt ?
Then how can I build my own box ?

Thanks :slight_smile:
