Do you object to the idea of having qemu call to a helper program directly or to the idea of having the helper program in qemu at all? Splitting the helper into a separate project may be a more constructive discussion as was suggested by Arnd. As a separate project, libvirt could also make use of it and use -net tap,fd= if it wanted to do crazy things. From a distro perspective, it's just a matter of setting up dependencies to make it Just Work so I don't object to it that much. It's just a bit annoying to create an entire new project for a few hundred line helper. -- Regards, Anthony Liguori
