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).
