Sure. Usually, when you are connecting locally ("qemu:///system" or
"qemu:///session") client and server talks on an unix socket. I forced
them to talk via loopback where I had wireshark running by:

1) configuring libvirtd to listen on network socket too (listen_tcp in
libvirtd.conf, passing --listen argument to the daemon cmdline)
2) connecting to qemu+tcp://localhost/system
