Like the log output says, virt-manager doesn't think your libvirt
instance supports remote bridge listing. You can test this by trying
the virsh iface-list command on the remote host: if it fails,
virt-manager was correct.

You'll want to make sure that libvirt was compiled with interface
support (using the netcf library) on both the local and remote host,
otherwise that code is disabled.
