How to prevent iptables from starting when libvirtd is started

Issue

• The Libvirtd process will add iptables rules into iptables when starting libvirtd.
• iptables will run when starting libvirtd, even if iptables was disable before .

# service iptables stop
iptables: Firewall is not running.

# service libvirtd restart

# service iptables status

table: filter
