Yes, I tried it on vif*.0. eth0 is the real network interface and is
not relevant (but I think I tried that too anyway and I didn't support
it).
You'll see in my followup mail that I found where the relevant code
was in the Xen network backend driver (which implements vif*) and it's
not conditional.
