Mac OS X Mountain Lion Host, VirtualBox 4.3.1, Network Adapter error for NAT Network

[Kenneth Wolcott]

Hi;

Brand-new installation of VirtualBox 4.3.1 downloaded from VirtualBox web site

Host is MacBook Pro 9,2 Mac OS X 10.9.4

Guest is CentOS 7.0

Problem: Unable to select any Network Adapter type other than NAT;
the error message is "Invalid settings detected" when "Name:" can only
have the setting "Not selected".

Perhaps my searching of the VirtualBox User Manual, the FAQ and the
Forums was not sophisticated enough as I did not find anything like
this being discussed already.

Interesting that I can successfully use yum to install from the web
on the VirtualBox guest using the NAT Network Adapter setting.

Please point me to the pertinent location in the User Manual and/or
a forum topic where this problem has already been discussed if it
exists.

Thanks,
Ken Wolcott

Hi;

I solved the problem with the help of WeblionX on IRC.

I needed to first define "NAT Network" and "Host-Only" via
VirtualBox->Preferences->Network.

Then I can define my Network Adapters (Nat Network and Host-Only) in
my Guest settings.

Thanks,
Ken
