#commit_net_config(opts = {}) ⇒ Object

Marks the network configuration as good and persists it inside the host.

An API user commits the network configuration to persist a host network interface attachment or detachment, or persist the creation and deletion of a bonded interface.

Important
Networking configuration is only committed after the engine has established that host connectivity is not lost as a result of the configuration changes. If host connectivity is lost, the host requires a reboot and automatically reverts to the previous networking configuration.

For example, to commit the network configuration of host with id 123 send a request like this:

POST /ovirt-engine/api/hosts/123/commitnetconfig

With a request body like this:

<action/>

Parameters:

  • opts (Hash) (defaults to: {})

    Additional options.

Options Hash (opts):

  • :async (Boolean)

    Indicates if the action should be performed asynchronously.

  • :headers (Hash) — default: {}

#setup_networks(opts = {}) ⇒ Object

This method is used to change the configuration of the network interfaces of a host.

For example, if you have a host with three network interfaces eth0, eth1 and eth2 and you want to configure a new bond using eth0 and eth1, and put a VLAN on top of it. Using a simple shell script and the curl command line HTTP client that can be done as follows:

#!/bin/sh -ex

Note
This is valid for version 4 of the API. In previous versions some elements were represented as XML attributes instead of XML elements. In particular the options and ip elements were represented as follows:
<options name="mode" value="4"/>
<options name="miimon" value="100"/>
<ip address="192.168.122.10" netmask="255.255.255.0"/>

# Find the service that manages the collection of hosts:
hosts_service = connection.system_service().hosts_service()

# Find the host:
host = hosts_service.list(search='name=myhost')[0]

# Find the service that manages the host:
host_service = hosts_service.host_service(host.id)
