NAT card inactive in ubuntu server

Post by centii »

I have Ubuntu 16.04 server as guest with one Host Adapter (only this works), one NAT and one Bridged.
I'm trying to see my virtual hosts in Apache.
From Guest:

I created a new guest of ubuntu desktop with a NAT adapter; that seems OK(?)

Please note that my Ubuntu server guest is blocked during apt-get update etc.
What should I do?
At the moment can't use my guest for developing...

Your guest only shows that you have the host-only adapter configured. You will need to correctly enable the NAT or Bridged adapter and configure them properly.

OK so you posted the result of ifconfig. Did you see that the only result was the host-only or are you saying that what you posted was exactly what you wanted to see?

From the hosts terminal type VBoxManage showvminfo <VM Name> --details and post here. Replace <VM Name> with the actual name of the VM. Use " " if the name has a space in it.

Then we can see what you really have configured.

Another strange thing is that I have cloned my guest some time ago before fiddling with it and I can see the NAT from ifconfig when enabled in the clone(!).

Please replace the output from NIC 3 empty to this one:

OK so your first reply clearly shows that you only have the host-only. I really need to see the complete one showing the necessary adapters if you expect me to be able to help you. Posting please replace does not work for me.

Re: NAT card inactive in ubuntu server

Now the guest has two ethernet adapters. All you should need to do is configure the second adapter. Since this is CLI there is no network manager to do this for you so you need to know how to manually setup the adapter with ifconfig eth* up and the proper settings. VirtualBox is passing the adapter through so it is now a configuration issue.
