No. Because the real host has no IPaddress associated with the interfaces used by the virtual hosts. For QEMU, make sure you manually set a unique MACaddress on the virtual interface. >> For proper results, you probably need two separate hosts *doing nothing >> but running iperf*.

Iperf / Re: [Iperf-users] Option to auto stop UDP traffic The important bit above is: "write2 failed: No route to host" There are other classes of failures that will not get detected, which something like keep alives would probably help with. However, there are no plans at this point to implement a keep alive system in Iperf. Hope that helps, Jon pkg update problem - "no route host" | The FreeBSD Forums 2017-7-27
