If you can rely on QEMU >= 0.12 then you should switch to using -netdev, since -net is going the way of the Dodo in upstream QEMU. eg -netdev user,id=hostnet0 -device virtio-net-pci,netdev=hostnet0,id=net0,mac=52:54:00:1b:a1:fc FWIW, I'd say this gives better performance, but with user mode that's not true. With TAP networking this syntax would allow for zero-copy since it eliminates the vlan multiplexor Regards, Daniel -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://deltacloud.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :|
