Answer 1

Hi @chard chitambo

You can restore back your VM after you replace network interface, doing this require a VM downtime.

1. Shutdown VM
2. Attach network interface - Create new network interface
3. Detach old network interface and delete
4. On the new network interface replace same old IP address and if any same details
5. power on VM

this will restore VM back to normal.

Hi,

Did you tried to reboot the VM after changing the DNS configuration?
