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:
- source
POST /ovirt-engine/api/hosts/123/commitnetconfig
With a request body like this:
- source,xml
<action/>
IMPORTANT: Since {engine-name} 4.3, it is possible to also specify `commit_on_success` in the xref:services-host-methods-setup_networks request, in which case the new configuration is automatically saved in the {hypervisor-name} upon completing the setup and re-establishing connectivity between the {hypervisor-name} and {engine-name}, and without waiting for a separate xref:services-host-methods-commit_net_config request.
@param opts [Hash] Additional options.

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:
- source
#!/bin/sh -ex
url=“engine.example.com/ovirt-engine/api” user=“admin@internal” password=“…”
curl \ –verbose \ –cacert /etc/pki/ovirt-engine/ca.pem \ –user “${user}:${password}” \ –request POST \ –header “Version: 4” \ –header “Content-Type: application/xml” \ –header “Accept: application/xml” \ –data ' <action>

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:
- source,xml
<options name=“mode” value=“4”/> <options name=“miimon” value=“100”/> <ip address=“192.168.122.10” netmask=“255.255.255.0”/>
The same thing can be done using the Python SDK with the following code:
- source,python
# 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’)
# Find the service that manages the host: host_service = hosts_service.host_service(host.id)
# Configure the network adding a bond with two slaves and attaching it to a # network with an static IP address: host_service.setup_networks(
modified_bonds=[ types.HostNic( name='bond0', bonding=types.Bonding( options=[ types.Option( name='mode', value='4', ), types.Option( name='miimon', value='100', ), ], slaves=[ types.HostNic( name='eth1', ), types.HostNic( name='eth2', ), ], ), ), ], modified_network_attachments=[ types.NetworkAttachment( network=types.Network( name='myvlan', ), host_nic=types.HostNic( name='bond0', ), ip_address_assignments=[ types.IpAddressAssignment( assignment_method=types.BootProtocol.STATIC, ip=types.Ip( address='192.168.122.10', netmask='255.255.255.0', ), ), ], dns_resolver_configuration=types.DnsResolverConfiguration( name_servers=[ '1.1.1.1', '2.2.2.2', ], ), ), ],
)
# After modifying the network configuration it is very important to make it # persistent: host_service.commit_net_config()
IMPORTANT: To make sure that the network configuration has been saved in the host, and that it will be applied when the host is rebooted, remember to call xref:services-host-methods-commit_net_config.
IMPORTANT: Since {engine-name} 4.3, it is possible to also specify `commit_on_success` in the xref:services-host-methods-setup_networks request, in which case the new configuration is automatically saved in the {hypervisor-name} upon completing the setup and re-establishing connectivity between the {hypervisor-name} and {engine-name}, and without waiting for a separate xref:services-host-methods-commit_net_config request.
