Traffic-mirror is a netfilter plugin.
It gives qemu the ability to copy and mirror guest's
net packet. we output packet to chardev.
usage:
-netdev tap,id=hn0
-chardev socket,id=mirror0,host=ip_primary,port=X,server,nowait
-traffic-mirror,id=m0,netdev=hn0,queue=tx/rx/all,outdev=mirror0

Thanks for the patch. Several questions:
- I'm curious about how the patch was tested? Simple setup e.g:
-netdev tap,id=hn0 -device virtio-net-pci,netdev=hn0 -chardev
socket,id=c0,host=localhost,port=4444,server,nowait -object
traffic-mirror,netdev=hn0,outdev=c0,id=f0 -netdev
socket,id=s0,connect=127.0.0.1:4444 -device e1000,netdev=s0
does not works for me.
Hi， Jason
I just test the mirror using the command line above, it don't work too.
I am looking to it, and find that seems because the -net socket problem that
I have ever post a patch try to fix（refer to ↓）
[Qemu-devel] [PATCH] report a error message if -net socket can not connect to
server
https://lists.gnu.org/archive/html/qemu-devel/2015-12/msg00758.html
after applying this patch, the qemu monitor tell me following message:
(qemu) qemu-system-x86_64: net socket is not connected Connection refused
Thanks
