Well, you miss the point that nwfilters is meant as a general firewall interface. ebtables/iptables just happens to be an implementation of this interface. Using ebtables/iptables specific shell scripts would replace the generic interface with something specific to ebtables/iptables. The general nwfilters interface allows to have an ebtables/iptables based implementation for the Linux based hypervisors and an ipfw based implementation for FreeBSD and other implementations that are specific to VirtualBox, ESX, Hyper-V, PowerHypervisor etc. How well the nwfilters interface maps to all those different firewalls is another question, but with this general interface there is at least the possibility to configure the different firewalls of different hypervisors via libvirt. -- Matthias Bolte http://photron.blogspot.com -- libvir-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/libvir-list
