Introduce virNetDevBandwidthUpdateFilter
This is a simple wrapper around virNetDevBandwidthManipulateFilter() that will update the desired filter on an interface (usually a network bridge) with a new MAC address. Although, the MAC address in question usually refers to some other interface - the one that the filter is constructed for. Yeah, hard to parse. Thing is, our NATed network has a bridge where some part of QoS takes place. And vNICs from guests are plugged into the bridge. However, if a guest decides to change the MAC of its vNIC, the corresponding qemu process emits an event which we can use to update the QoS configuration based on the new MAC address.. However, our QoS hierarchy is currently not notified, therefore it falls apart. This function (when called in response to the aforementioned event) will update our QoS hierarchy and duct tape it together again. Signed-off-by: Michal Privoznik <mprivozn@redhat.com>
LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed. Daniel Veillard <veillard@redhat.com>
Description
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.
