> You don't have to restart the guest to add or remove aliases:

yes I am aware of that, and that's why I'm wondering whether it is
better to use aliases rather than to add virtual interfaces (which
does require to restart guests with our KVM version, no hot-plug I
think).

But is there any drawback with using aliases?
Or does using virtual interfaces provide additional performance/stability/... ?
