[libvirt-users] KVM + libvirt + nftables without iptables?

Hi everyone, I use Debian 9.5 Stretch and NFTABLES as a firewall. Using NFTABLES together with IPTABLES is not recommended, but libvirt depends on IPTABLES. Is it safe to run libvirt + kvm + virsh without IPTABLES? By the doc https://libvirt.org/firewall.html, IPTABLES are used for settingup filtering which I do not need. Thanks, Roman
