Making /var/lib/libvirt/images a Btrfs Subvolume?

I recently installed Arch Linux using Btrfs and I made a subvolume for /var/lib/libvirt/images and called it @images. Now I'm thinking I should've made the entire /var/lib/libvirt a subvolume not just the images directory because there may be stuff in the libvirt directory that the virtual machine images rely on and the bridge network and other stuff won't be snapshotted. Do you think I should make /var/lib/libvirt a subvolume instead? The reason why I want to make /var/lib/libvirt or /var/lib/libvirt/images a subvolume is because I don't want my virtual machines to get snapshotted and lose them on a snapper rollback. If I need to make the entire libvirt directory a subvolume, how do I do that? Here is my Btrfs subvolume list

Also, I'm having trouble with creating a network bridge for KVM. I get confused at the IP address stuff. Am I supposed to use my IP address? when I was installing KVM in Arch Linux I couldn't install the package ebtables because aparently it has been moved the the AUR and when I try to install the AUR package it tried to install iptables-nft instead. Also, when looking at the virt-viwer package on Arch Linux website it shows it was last updated in 2021 which worries me.
