## Synopsis

- Module to manage host networks in oVirt/RHV.

## Requirements

The below requirements are needed on the host that executes this module.

- python >= 2.7
- ovirt-engine-sdk-python >= 4.3.0

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
auth dictionary / required |  | Dictionary with values needed to create HTTP/HTTPS connection to oVirt:
| ca_file string |  | A PEM file containing the trusted CA certificates. The certificate presented by the server will be verified using these CA certificates. If `ca_file` parameter is not set, system wide CA certificate store is used. Default value is set by `OVIRT_CAFILE` environment variable.
| headers dictionary |  | Dictionary of HTTP headers to be added to each API call.
| hostname string |  | A string containing the hostname of the server, usually something like `server.example.com`. Default value is set by `OVIRT_HOSTNAME` environment variable. Either `url` or `hostname` is required.

insecure
boolean

Choices:
- no
- yes

A boolean flag that indicates if the server TLS certificate and host name should be checked.

kerberos
boolean

Choices:
- no
- yes

A boolean flag indicating if Kerberos authentication should be used instead of the default basic authentication.

| password string / required |  | The password of the user. Default value is set by `OVIRT_PASSWORD` environment variable.
| token string |  | Token to be used instead of login with username/password. Default value is set by `OVIRT_TOKEN` environment variable.
| url string |  | A string containing the API URL of the server, usually something like `https://server.example.com/ovirt-engine/api`. Default value is set by `OVIRT_URL` environment variable. Either `url` or `hostname` is required.
| username string / required |  | The name of the user, something like admin@internal. Default value is set by `OVIRT_USERNAME` environment variable.
bond - |  | Dictionary describing network bond: `name` - Bond name. `mode` - Bonding mode. `options` - Bonding options. `interfaces` - List of interfaces to create a bond.

check
boolean

Choices:
- no
- yes

If true verify connectivity between host and engine.
Network configuration changes will be rolled back if connectivity between engine and the host is lost after changing network configuration.

fetch_nested
boolean

Choices:
- no
- yes

If True the module will fetch additional data from the API.
It will fetch IDs of the VMs disks, snapshots, etc. User can configure to fetch other attributes of the nested entities by specifying `nested_attributes`.

interface - |  | Name of the network interface where logical network should be attached.
labels - |  | List of names of the network label to be assigned to bond or interface.
name - / required |  | Name of the host to manage networks for. aliases: host
nested_attributes list |  | Specifies list of the attributes which should be fetched from the API. This parameter apply only when `fetch_nested` is true.

networks
-

List of dictionary describing networks to be attached to interface or bond:
`name` - Name of the logical network to be assigned to bond or interface.
`boot_protocol` - Boot protocol one of the none, static or dhcp.
`address` - IP address in case of static boot protocol is used.
`netmask` - Subnet mask in case of static boot protocol is used.
`gateway` - Gateway in case of static boot protocol is used.
`version` - IP version. Either v4 or v6. Default is v4.

poll_interval integer | Default: 3 | Number of the seconds the module waits until another poll request on entity status is sent.

save
boolean

Choices:
- no
- yes ←

If true network configuration will be persistent, otherwise it is temporary. Default true since Ansible 2.8.

state
-

Choices:
- present ←
- absent

Should the host be present/absent.

sync_networks
boolean
added in 2.8

Choices:
- no ←
- yes

If true all networks will be synchronized before modification

timeout integer | Default: 180 | The amount of time in seconds the module should wait for the instance to get into desired state.

wait
boolean

Choices:
- no
- yes ←

`yes` if the module should wait for the entity to get into desired state.

## Notes

Note

- In order to use this module you have to install oVirt Python SDK. To ensure it’s installed with correct version you can create the following task: pip: name=ovirt-engine-sdk-python version=4.3.0

## Examples

    # Examples don't contain auth parameter for simplicity,
    # look at ovirt_auth module to see how to reuse authentication:

    # In all examples the durability of the configuration created is dependent on the 'save' option value:

    # Create bond on eth0 and eth1 interface, and put 'myvlan' network on top of it and persist the new configuration:
    - name: Bonds
      ovirt_host_network:
        name: myhost
        save: yes
        bond:
          name: bond0
          mode: 2
          interfaces:
            - eth1
            - eth2
        networks:
          - name: myvlan
            boot_protocol: static
            address: 1.2.3.4
            netmask: 255.255.255.0
            gateway: 1.2.3.4
            version: v4

    # Create bond on eth1 and eth2 interface, specifiyng both mode and miimon:
    - name: Bonds
      ovirt_host_network:
        name: myhost
        bond:
          name: bond0
          mode: 1
          options:
            miimon: 200
          interfaces:
            - eth1
            - eth2

    # Remove bond0 bond from host interfaces:
    - ovirt_host_network:
        state: absent
        name: myhost
        bond:
          name: bond0

    # Assign myvlan1 and myvlan2 vlans to host eth0 interface:
    - ovirt_host_network:
        name: myhost
        interface: eth0
        networks:
          - name: myvlan1
          - name: myvlan2

    # Remove myvlan2 vlan from host eth0 interface:
    - ovirt_host_network:
        state: absent
        name: myhost
        interface: eth0
        networks:
          - name: myvlan2

    # Remove all networks/vlans from host eth0 interface:
    - ovirt_host_network:
        state: absent
        name: myhost
        interface: eth0

## Return Values

Common return values are documented here, the following are the fields unique to this module:

Key | Returned | Description
--- | --- | ---
host_nic dictionary | On success if host NIC is found. | Dictionary of all the host NIC attributes. Host NIC attributes can be found on your oVirt/RHV instance at following url: http://ovirt.github.io/ovirt-engine-api-model/master/#types/host_nic.
id string | On success if host NIC is found. | ID of the host NIC which is managed Sample: 7de90f31-222c-436c-a1ca-7e655bd5b60c
