To connect your virtual routers to RouterOS host system you either have to assign interface for your guest (possible only on MetaROUTER) or you can add virtual Ethernet interface that is described in this document.
May contain either static or dynamic interface. Static interfaces should be configured here if under /kvm interface (for [[Kvm|KVM) or /metarouter interface for MetaROUTER. Dynamic interfaces will be recreated automatically each reboot and will contain new MAC address.
Menu is only available if KVM package is installed on x86 architecture, or on RouterOS running on selected RouterBOARDS.
