Hi, all. I want to add tap device to br-ex rather than linux bridge when attaching an interface to a vm. I find some code in nova/virt/libvirt/vif.py in function plug_ovs_hybrid like this " utils.execute('brctl', 'addbr', br_name, run_as_root=True) ". I find no place which add tap device to linux bridge. Does libvirt do it? Could some helps me? thx. -------------- next part -------------- An HTML attachment was scrubbed...
