Re: [libvirt] [PATCH] virsh-domain: update attach-interface to support bridge type

Adding this feature will allow users to attach a network to linux bridge or openvswitch. The interface can be attached using --brtype=linux or --brtype=openvswitch. If --brtype is not set, the network is attached to linux bridge.
