A method relates to receiving, by a processing device of a host computer system executing a hypervisor, a network packet from a virtual port associated with a virtual machine managed by the hypervisor, generating a metadata item associated with the network packet, the metadata item comprising an identifier of the virtual port, recording the metadata item in a data structure identifying an address space of the hypervisor, determining, in view of the metadata item, a transmission mode to transmit the network packet, wherein the transmission mode is represented by at least one of a link aggregation mode or a high availability mode, identifying a network interface controller (NIC) of the host machine for processing the network packet according to the transmission mode, transmitting the network packet to the NIC.
