Description of problem: Creation of the instance fails with [1] from compute nova logs(nova-compute.log) on file:comp_logs.tar [1] [instance: 28b5f6f6-543e-49cf-946e-fc59810d6755] Instance failed to spawn: nova.exception.VirtualInterfaceCreateException: Virtual Interface creation failed Version-Release number of selected component (if applicable): OSP-16.2.4 Details: The SDN soln is cisco-aci and vendor(Cicso) has drill down that the issue is due to "Nova event matching" which is missing after network-vif-plugged action is completed as we can see on controller logs[2].

Actual results: - Want to confirm if the issue is same as in https://bugzilla.redhat.com/show_bug.cgi?id=2135363 Expected results: - Want instance creation to get successful at first attempt Additional info: - This is single controller deployment and not yet put to production. - SOS of controller, compute and instance details in 0050-03455213_1003.tar. - Findings from cisco team attached.
