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.

The virMacMap module is there for dumping [domain, <list of is MACs>] pairs into a file so that libvirt_guest NSS module can use it. Whenever a interface is allocated from network (e.g. on domain<F2> startup or NIC hotplug), network is notified and so is virMacMap module subsequently. The module update functions networkMacMgrAdd() and networkMacMgrDel() gracefully handle the case when there's no module. The problem is, the module is created if and only if network is freshly started, or if the daemon restarts and network previously had the module. This is not very user friendly - if users want to use the NSS module they need to destroy their network and bring it up again (and subsequently all the domains using it). One disadvantage of this approach implemented here is that one may get just partial results: any already running network does not record mac maps, thus only newly plugged domains will be stored in the module. The network restart scenario is not touched by this of course. But one can argue that older libvirts had never recorded the mac maps anyway. 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.
