Hi,

With Ussuri, when launch VM, I see this from nova-compute.
========
Received unexpected event network-vif-plugged-32b7af8a-ef81-4785-bd79-3a5619823638
========

That caused VM to be destroyed, rescheduled and relaunched. And that recreation worked fine.
>From user POV, it just takes a bit longer to launch the VM.
What's the event nova-compute expects from Neutron for vif-plug?
Any hints where I can look into it?

More logs here.
