Laine Stump a4f38f6ffe network: use iif/oif instead of iifname/oifname in nftables rules
iifname/oifname need to lookup the string that contains the name of
the interface each time a packet is checked, while iif/oif compare the
ifindex of the interface, which is included directly in the
packet. Conveniently, the rule is created using the *name* of the
interface (which gets converted to ifindex as the rule is added), so
no extra work is required other than changing the commandline option.

If it was the case that the interface could be deleted and re-added
during the life of the rule, we would have to use Xifname (since
deleting and re-adding the interface would result in ifindex
changing), but for our uses this never happens, so Xif works for us,
and undoubtedly improves performance by at least 0.0000001%.

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.
