To use drivers for paravirtualized network devices you have to choose VirtIO as the type of the network interface in web admin gui for the VM and probably reconfigure it inside the OS because it will be detected as a new one and will lose previous configuration. You can also use (at install time or later) paravirtualized drivers for disks. HIH, Gianluca
