Long ago we adapted to iptables changes by introducing support for '-m conntrack': commit 06844ccbaa8544d7d08d568aff37bc4e3648f304 Author: Stefan Berger <stefanb@us.ibm.com> Date: Tue Aug 6 20:30:46 2013 -0400 nwfilter: Use -m conntrack rather than -m state Since iptables version 1.4.16 '-m state --state NEW' is converted to '-m conntrack --ctstate NEW'. Therefore, when encountering this or later versions of iptables use '-m conntrack --ctstate'. Given our supported platform targets, we no longer need to consider a version of iptables before 1.4.16, so can drop support for the old syntax. The test suite updates are triggered because that never probed for the new syntax, and so unconditionally generated the old syntax.

Libvirt API for virtualization
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
