[libvirt] Feature Request: sniff a virtual interface of a guest

Hi, there is currently no support for sniffing the network traffic of a virtual nic, from local or remote. In some cases the debugging or monitoring of a guest is therefore not as easy as it could be. Although it's easy to start a network sniffer on the physical host, it requires direct access to a shell and some knowledge of the current configuration of the virtual networks. I think it would be a great benefit for libvirt if network sniffing would be possible out of the box. One idea would be to start a local tshark sniffing on the card and connect this to a local socket. This could then be forwarded by ssh to a wireshark process running on a desktop. I created a feature request for that: https://bugzilla.redhat.com/show_bug.cgi?id=784893 Any thoughts or hints to implement that? Hendrik Schwartke
