When fetching stats for a domain's <interface/>, or when setting up its QoS, we can face two situations: 1) the device "shares" the host view, meaning each packet sent/received on the interface by a domain is accounted for in the same category on the host, or 2) the device is at the other side, and a packet send by a domain, is in fact packet received on the host. This fact affects whether we need to swap RX/TX values when fetching stats, or setting up QoS. We have this convenient helper function (virDomainNetTypeSharesHostView()), which returns to which category given interface type falls into. Now, for unmanaged type='ethernet' our options are quite limited, because it's user's responsibility to set up the host side of the interface. And it can be just anything. Fortunately, we have another convenience function (virNetDevMacVLanIsMacvtap()), which determines whether given interface is a macvtap (which is notoriously known for falling into the first category). Let's use it to help virDomainNetTypeSharesHostView() determine the view more accurately.

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.
