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.

Laine Stump fe7872827f virsh: new net-update command
This command uses the new virNetworkUpdate() API to modify an existing
network definition, and optionally have those modifications take
effect immediately without restarting the network.

An example usage:

  virsh net-update mynet add-last ip-dhcp-host \
   "<host mac='00:11:22:33:44:55' ip='192.168.122.45'/>" \
   --live --config

If you like, you can instead put the xml into a file, and call like
this:

  virsh net-update mynet add ip-dhcp-host /tmp/myxml.xml
   --live --config

virsh will autodetect whether the argument is itself an xml element,
or if it's a file, by looking at the first character - the first
character of an xml element is always "<", and the first character of
a file is almost always *not* "<" (in the rare case that it is, the
user could specify "./<filename...").

A --parent-index option is also available (to give the index within a
list of parent objects, e.g. the index of the parent <ip> element when
updating ip-dhcp-host elements), but is optional and at least for now
will probably be used rarely.

--live, --config, and --current options - if you specify --live, only
the live state of the network will be updated. If you also specify
--config, then the persistent configuration will also be updated;
these two commands can be given separately, or both together. If you
don't specify either (you can optionally specify "--current" for the
same effect), then the "current" config will be updated (i.e. if the
network is active, then only its live config is affected, but if the
network is inactive, only the persistent config is affected).

         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.
