Prior to firewalld version 1.0.0, the default action of ACCEPT in the "libvirt" zone (subsequently overridden with a lower priority "REJECT" action) would result in an implicit rule that allowed incoming sessions through the zone; libvirt relied on this implicit rule to permit incoming connections to guests that were connected via a libvirt "routed" network. Starting in firewalld 1.0.0, the rules generated for this same zonefile changed such that incoming sessions through the libvirt zone were no longer allowed, breaking the longstanding convention that they should be allowed (only for routed networks). However, beginning with firewalld 0.9.0, a zone can explicitly allow/block forwarded traffic (by adding a "policy" to the zone that specifies what happens to packets that are going in one zone and out another zone). This patch changes the zone for routed networks from "libvirt" to the newly-added "libvirt-routed" zone that uses the new policy functionality to once again allow incoming sessions to guests on routed networks. (If firewalld is < 0.9.0, then the policy file won't be read at all, so firewalld won't log any error, and libvirt will just use the old setup that takes advantage of the implicit forwarding rules).

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.
