Static IP addresses for Virtualbox Bridged connections are set up in the VM's OS, not in any Virtualbox setting. You would web-search your VM OS's help manuals and forums to find out how to set a static IP address, and set the adapter in the VM OS that is the bridged adapter, inside the VM's OS.

I am seeing this issue, using my laptop host in a different home (different WiFi.) Ordinarily this works fine and I've used this host+guest in multiple locations with no issues, but no luck this time. I'd appreciate any pointers.

I've used this type of setup (Windows host + Ubuntu guest) at this location before, but this is a new host, and the guest configuration might also be different.

Never mind -- I change the guest's VBox Network mode from Bridged to NAT and all seems OK. I believed I used Bridged mode to enable IP traffic between host and guest, but I don't need that now.
UPDATE: The reason I used Bridged mode is to allow the guest to use the host's VPN tunnel. Of course, I can set up the same tunnel under Ubuntu, but if there's an easy way to get bridged mode working please let me know.

That won't work. Two PCs cannot share one end of a VPN connection: you can only use the host's VPN if you use NAT, because in that case the VM is actually using the host's Internet connection.

Hi, I'm going through same problem 'Activation of Network connection failed'.
However it only happens if I try to use other host only adapters except the first one.
To give a clear picture i have following host only adapters and I got multiple machines which I want to be connected on different Host-Only adapters.
1. VirtualBox Host-Only Ethernet Adapter
2. VirtualBox Host-Only Ethernet Adapter #2
3. VirtualBox Host-Only Ethernet Adapter #3
4. VirtualBox Host-Only Ethernet Adapter #4
I tried using these adapter on other machines and issue remains the same.
When I did "VBoxManage list dhcpservers", Only first adapter has the DhcpId IP and all others shows 0.0.0.0. Refer to the dhcpservers file attached.
I think this might be the issues but not sure and dont know how to fix. Hope someone can help me out thanks.
