Since we previously only supported vlan tagging for interfaces connected to an OVS bridge [*], the code in qemuChangeNet() (used by the update-device API) assumed an interface with modified vlan config was on an OVS bridge, and would call the OVS-specific virNetDevOpenvswitchUpdateVlan(). Now that we support vlan tagging for interfaces connected to a standard Linux host bridge, we must check the type of connection and only call the OVS function when connected to an OVS bridge *both before and after the update*. Otherwise we just set the flag to re-connect to the bridge, which has the side effect of redoing the vlan setup. ([*] or an SRIOV VF assigned using VFIO, but we don't support *any runtime changes to that type of netdev so it's irrelevant here.)

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.
