The key is to make the virtio-net devices multifunction and to

This is unlikely to work right wrt pci hotplug.
Yes. Our hotplug design is based on devices.. This is wrong, it
should be based on bus-level concepts (like PCI slots).
If we want to support a large number of interfaces, we need true
multiport cards.
This magic here creates a multiport virtio-net card so I'm not
really sure what you're suggesting. It would certainly be nice to
make this all more user friendly (and make hotplug work).
The big issue is to fix hotplug.
Yes, but this is entirely independent of multifunction devices.
Today we shoe-horn hot remove into device_del. Instead, we should
have explicit bus-level interfaces for hot remove.
I'm not saying multiplug is not the right way to approach this (it is).
The only concern is to get hotplug right.
