This seems like a really interesting idea, and something I've thought about for
a while. Could you elaborate a little more on what you think the VHW
functionality might entail? Is it specific to the kernel?
I somewhat imagine a Genode system running over a network with different kernels
per-device, so in that scenario it'd be a network VHW.
On another note, this is some really great work being done, I'm excited to see
what comes of it- Perhaps the next Qubes OS for x86_64.
