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).

You said it backwards originally. You said that aliases required restarts. ;)

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

I've never had issues with aliases. They 'just work'. I use hundreds of them.
