end
commit_net_config(opts = {}) click to toggle source

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

setup_networks(opts = {}) click to toggle source

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

For example, lets assume that you have a host with three network interfaces `eth0`, `eth1` and `eth2` and that 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

Note that 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

Using the Python SDK the same can be done with the following code:

# 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)
