How to let only virtual machine (kvm) traffic through openvpn on the host?

Question

openvpn

Greetings!
Launched a virtual machine behind NAT on KVM.
I am running openvpn on the host. How to make sure that only virtual machine traffic passes through the VPN, for example, from the Virbr1 interface.
Well, or vice versa, how to exclude the passage of host traffic through vpn, but only VM.
And yes, there is no way to run openvpn on a guest.
