Date: Fri, 8 Nov 2019 15:44:07 -0800 Message-ID: <firstname.lastname@example.org> (raw) When I create a virtio-user device with rte_hotplug it creates a kernel device (ie vtap0). This is normal an the device has ifindex N. But later when device is configured an started the original vtap0 device is deleted and a new one is created (with ifindex N+1). This seems like a bug, if nothing else it unnecessary overhead and link flapping for routing daemons. Noticed only while tracking down a bug where after vtap was created the address was being set, but then disappearing. Is this intentional? Is it documented?
