[Question] Securely Passing Host VPN to KVM? (lemmy.ml)

I've attempted to create a VM on my ubuntu host machine that is accessing the internet via a dedicated VPN app. I'm able to disconnect my host VPN and access the web within the VM, but cannot access the web when the host VPN is enabled. Ideally I'd like to enable the VPN on the host and pass through web access to the VM.

I have two questions:

If my use case is to use a VM to increase privacy and security as well as isolate my operations within the VM from my host, is it better to have the VPN app from inside the VM or pass the host's through to the VM?
If it doesn't make much of a difference, how can I go about passing the host's VPN to the VM?

In either scenario, I'd still like to keep the host's VPN active while being able to use the VM, which I currently cannot.

The moment your VPN app starts it will change gateway and name servers for your host. If the virtual NIC of your VM is bridged with your host I would expect it to work fine for the VM. Is this with KVM or Qemu or VirtualBox or something else ? How is networking configured ?

QEMU. Using NAT but it's attached to the host's NIC. I know this is probably what's causing the issue. I'm not sure how to connect it to the VPN.
