In one of my recent commits, I've introduced
virDomainInterfaceClearQoS() which is a helper that either calls
virNetDevBandwidthClear() ('tc' implementation) or
virNetDevOpenvswitchInterfaceClearQos() (for ovs ifaces). But I
made a micro optimization which leads to a bug: the function
checks whether passed iface has any QoS set and returns early if
it has none. In majority of cases this is right thing to do, but
when removing QoS on virDomainUpdateDeviceFlags() this is
problematic. The new definition (passed as argument to
virDomainInterfaceClearQoS()) contains no QoS (because user
requested its removal) and thus instead of removing the old QoS
setting nothing is done.
Fortunately, the fix is simple - pass olddev which contains the
old QoS setting.

==============================
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.
