We have to *understand* the code.  If we don't, we need to rewrite the
code so we *do* understand it, or make way for someone who does.

I'm looking at the kvm man page to try to figure out how to have virtio
console, and it's deeply unclear.  What kvm commandline are you using?
I'll try to debug it here, and see what I learn about hvc_console.

Cheers,
Rusty.
