***...and that is not enough, ALL of the following commands need to be run for configuration changes to take effect (the below examples assume ''default'' is the name of the network device) | |||
****virsh net-destroy default (essentially stops the device, and also deletes it, as apparently restarting it alone isn't enough) | |||
****virsh net-define default (in reality, the intent is to 're-define' the interface, but from the VIRTLIBD perspective the interface has been 'destroyed' and isn't there, so it needs to be defined) | |||
****virsh net-start default | |||
****Note: Hey, I've got an idea for you genzers that are programming this, why not create a virsh net-restart command that intuitively does what a bazillion other past command examples do to complete the above task? | |||
