While we could argue about this my feeling is that we should drop this,

any Davide-acceptable alternatives.
In the meanwhile, we can let vhost-net support edge-triggered interrupts
only, let qemu terminate those eventfds and convert then to
level-triggered interrupts (which it can then inject using the existing
ioctl). It will keep vhost-net and kvm simpler at the cost of some
performance penalty to guests using level interrupts. These suck anyway
so we'll point users at msi.
I thought the point was to move assigned devices out of KVM?
Grr. Forgot about that.
That's much more important.
