[libvirt-users] Virtual Netwok manager and cmd

Dear All, I'm reading the following pages: http://wiki.libvirt.org/page/TaskRoutedNetworkSetupVirtManager http://wiki.libvirt.org/page/TaskNATSetupVirtManager http://wiki.libvirt.org/page/TaskIsolatedNetworkSetupVirtManager routed mode, NAT mode and Isolated mode, But above pages explain with GUI, a sysadmin forgets GUI... Question is What's replacement of above command? ---Best Regards Mohsen
