I have a problem with my virtualbox on ubuntu 12.04, I can't add a host only adapter, the message is "no host only network adapter selected" I can't select anything
can anyone solve this problem??
Probably, the virtual host-only network wasn't set up yet. Here's is how you can fix this:
Normally, the settings of the new network will be ok, but for completeness, I give the default values here. You can access the settings for the host-only network through the screwdriver button on the right.
You can change these settings to your liking, as long as they're consistent.
For those, who are in trouble finding "Host-only Networks" tab in File->Preferences->Network.
After the version VirtualBox 5.2.0, there are some changes with the location of "Host-only Networks" tab.
This tool is moved on the main UI toolbar, specifically the Global Tools split button on the right.
Alternatively, you can access it via Ctrl+W, or File->Host Network Manager menu.
