The article is literally contentless. It doesn't answer its own question. I don't know if its AI generated or a marketing fluff piece. Virtio is nothing but an interface/protocol and won't magically make your VMs any different -- in fact it was already commonly used in x86 VMs.
...you actually think a notable Apple-centric blog is AI-generated nonsense?
Am I reading this right?
It does have a lot of confusing or downright wrong content. Saying that it's hallucinations is in some sense a compliment to the author...
