Steps I followed to have my windows 10 host connect to Fedora 26 guest with static IP though host-only adapter and also allow the VM to connect to Internet through the host.

In VM VirtualBox,

    1. File -> Preferences -> Network 
        
       NAT Networks tab
       ------------------   
        a. Hit the icon for 'Adds new NAT network'.
        b. Wait till a new NAT Network adapter is created and added to the list. For me, it was named as 'NatNetwork'.
