Since [1], all ports used as virtual IP ports, as marked as virtual in the OVN NB: LSP.type=virtual A virtual port is used to reserve an IP address in a network. When this IP address is assigned as "allowed address" to another port, the ML2/OVN mech driver detects that the virtual port has parents [2] and sets the port type. These ports cannot be used as VM ports because of this: these are virtual ports from OVN point of view. These ports cannot be bound and are just a representation of this VIP. The OVN SB "Port_Binding" register (that reflects the type=virtual mark), is assigned to a chassis by the ovn-controller, when an ARP packet with the VIP crosses a compute integration bridge. In other words: if many VM ports have this "allowed address" VIP (as a floating VIP between several ports), the port transmitting with this IP (can be only one) will claim the chassis.
