[bug#29281] [PATCH] system: vm: Use linux-libre for system-disk-image.

[Mathieu Othacehe]

Oh, why is that?  You mean qemu-system-arm running natively on the BBB,
right?

Yes, when running qemu-system-arm you have only a limited set of available machines (qemu-system-arm -M help).

BBB isn't one of them, but as there are only about 50 emulable machines, it will be the case for many other boards :(

In a future patch, I'll adapt "load-in-linux-vm" to use "-M virt" for qemu-system-arm because contrary to most boards,

it works well with linux-libre, allows up to 8 CPU, virtio (see https://wiki.qemu.org/Documentation/Platforms/ARM) ...

However, I don't think qemu virt machine will boot with every specific arm kernel a user might end up using

on his target.

Perhaps we should change ‘system-disk-image’ to use a more minimalistic
initrd since all it needs is those virtio* drivers?

That would be an option for the initrd, but the kernel problem above remains :)

Thanks !

Thanks for explaining!
