[libvirt] Is qemu guestfwd working?

Hi, How is guestfwd working? I am testing with the following domain xml snippet, which should let the guest connect to 10.0.2.1:4600 <channel type='unix'> <source mode='connect' path='/tmp/guestfwd'/> <target type='guestfwd' address='10.0.2.1' port='4600'/> </channel> If I have a domain with bridge networking, adding guestfwd isn't going to work, unless I am missing something. Should libvirt prevent that? But even if I use user networking, guestfwd will create a separate netdev, which isn't connected to any peer (both at cold and hot plug time) How is it supposed to work? thanks -- Marc-André Lureau
