If Linux's errnos are stable, we could just use them and let a
non-Linux guest define a set of KVM_E2BIG, etc.? It just seemed
pretty ugly to add a bunch of these.
The ugliness will serve to remind us that this is a potentially
non-Linux path.
In this particular case, the names are not present in guest-visible
headers, but any other that is made visible must have a
non-Linux-dependent name, so I don't see why error numbers should be
treated specially.
Ok.
