I've been trying to get my Ubuntu or my Android VMs to access a VPN I have running on the host without any luck.
The VPN works and everything checks out on the host, but if I try to connect to sites I know are restricted in the country I'm in, inside the VM,
the connection fails, indicating that the VPN is not used in the VM.

I've spent quite a lot of time trying to get this to work, including trying to use the Host-only adapter without any luck. Anyone know how to get this to work? Or is it not even possible?

VPN connections usually can't be shared. If you want the guest to use a VPN connection set up the VPN client in the guest OS.
