Huge implications. I’m wondering what the security implications are here though, especially in a Hypervisor context.

I assume you would be operating VNFs in the context of using these parameters, which implies that any security concerns would be mitigated through the use of the same.

I would agree, but if I’m looking for a way to work a payload into userspace, this sounds like a good attack vector. It’s not even code complete yet, I’m just curious. The speedups are fantastic, I just want to see where the logic goes to handle protections for non-base/metal comms.
