"no host only network adapter selected"
This is when I try to configure my vritual machines.
In VirtualBox terms, this is a standard and expected bit of virtual kit, and the application complains if it doesn't find one.
Usually, this message means the virtual host-only network wasn't set up. This operates at system-level, not individual virtual machine so it looks like a serious breakage in virtualbox. It isn't.
You can set this up manually yourself:
- From the main menu, select File > Preferences (Ctrl+G) - it's not in the settings of a single virtual machine.Select Network in the list on the left
- You will see an empty white box with "Host-only Networks" at the top. To the right are three buttons to manage them.
- Click the topmost network adapter icon with a green 'plus' symbol. A new Host-only network will be created and added to the list - this is generally named vboxnet0 by the installer but it could be anything.
IPv4 address: 192.168.56.1
IPv4 Network Mask: 255.255.255.0
More importantly the error message goes away and you have Host-only networking capability back. RC
