No, QEMU passes the raw messages to the backend daemon running in host userspace (which shares a socket with qemu). The backend understands the virtio/vhost protocols and so won't be required to change at all if we move from Qemu to something else. And that's what we (Linaro) are looking to do here with Project Stratos.
This is one of the ways of using it, via a backend running in host userspace, maybe there are other ways of making this work which I may not have explored, like handling this within qemu.
Note that this is completely different from my approach that I've posted in autumn last year. Viresh's protocol hasn't much in common with mine.
The protocol hasn't changed in a sense on how it can be used. Yes few things have moved around, new operations were introduced, but nothing that will make a change at this level. We are trying to use the protocol in one of the possible ways and yours can be different. -- viresh _______________________________________________ Virtualization mailing list Virtualization@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/virtualization
