passed in from the higher levels – iirc, we default to using ‘tcfilter’ at the moment. Have a look in the config file for some more info.<o:p></o:p></span></font></p>

networking correctly as it would for say ‘runc’, then kata should pick that up and translate/re-configure it into the VM and host side so it works ‘seamlessly’.<o:p></o:p></span></font></p>
