Good morning, I tried hot add and configure a second interface (the installation appliance mark to reserved for HA) and it has stopped working. After reverting the snapshot I have added again the second interface that the appliance reserves for HA and I have not configured it. I've added a third internal card (Host-only) and configured it with my private lab network configuration, and configured with my windows domain controller for dns resolution, firewall virtual appliance for gateway and time server against the PDC:



I access from the two networks without problems, and I have added the esxi with name resolution.
I will try later to disable the bridged interface, as in my old installations of version 6.7, to see if it doesn't stop working. I want to configure the Internet access only through the virtual appliance of the laboratory.
With this method, stage 2 ends in five minutes, in one of the many trys I have waited more than 3 hours in the 84% part and it has not finished.
I hope it helps you.
