Are you doing nat rules? How the ip will correspond to the guest?
– Luciano Andress Martini

I guess I'm missing the point of your question. This appears to be very basic networking, on the surface. Debian guest, ens3 is assigned 192.168.122.202. Lubuntu host, virbr0 is assigned 192.168.122.1. If you check the ip route and related settings on Debian, you will see the gateway address for Debian is 192.168.122.1. This is normal and more-or-less default behavior for libvirt/KVM/QEMU on Debian and Enterprise Linux based distros, in my experience.

Are you doing nat rules? How the ip will correspond to the guest?
– Luciano Andress Martini

I guess I'm missing the point of your question. This appears to be very basic networking, on the surface. Debian guest, ens3 is assigned 192.168.122.202. Lubuntu host, virbr0 is assigned 192.168.122.1. If you check the ip route and related settings on Debian, you will see the gateway address for Debian is 192.168.122.1. This is normal and more-or-less default behavior for libvirt/KVM/QEMU on Debian and Enterprise Linux based distros, in my experience.

Your guest has one non-loopback interface, ens3; that’s the interface it uses to communicate with the host. On the host, the matching interface is the interface in the same network, which is virbr0 here. If you want to list the interfaces which are part of the bridge, run
brctl run virbr0
on the host.
You can also match the routes in the guest to the host: the guest’s gateway will be the host. To see the routes, run
ip route list
The default gateway is given on the “default” line, something like
default via 192.168.122.1 dev ens3 proto static metric 100
