This action updates all specified host network resources with standard NIC elements. The request includes additional elements specified in the following table.
| Element | Type | Description |
|---|---|---|
modified_bonds | complex | Creates or updates bonds. Each host_nic element contains standard bonding elements. See Section 14.7.2.2, “Bonded Interfaces”. |
removed_bonds | complex | An ID list of bonds to remove. |
modified_network_attachments | complex | Adds or updates network attachments on the host. Each network_attachment element contains standard host network_attachment elements. See Section 14.7.1, “Host Network Attachments Sub-Collection”. Changing the host_nic ID moves the network to a different network interface card. |
synchronized_network_attachments | complex | An ID list of out-of-sync network attachments to synchronize with the logical network definition of the data center. |
removed_network_attachments | complex | An ID list of network attachments to remove. |
modified_labels | complex | Creates or modifies labels. Each label element contains a label id (when creating a label) and a host_nic identified by a name or ID. Changing the host_nic ID moves the label to a different network interface card. |
removed_labels | complex | An ID list of labels to remove. |
checkConnectivity | Boolean | Set to true to verify connectivity between the host and the Red Hat Virtualization Manager. If the connectivity is lost, Red Hat Virtualization Manager reverts the settings. |
connectivityTimeout | integer | Defines the timeout for loss of connectivity. |
14.8.4. Fence Host Action
An API user controls a host's power management device with the
fence action. The capabilities lists available fence_type options.
Example 14.31. Action to fence a host
POST /ovirt-engine/api/hosts/2ab5e1da-b726-4274-bbf7-0a42b16a0fc3/fence
Accept: application/xml
Content-Type: application/xml
<action>
<fence_type>start</fence_type>
</action>
14.8.5. Deactivate Host Action
Deactivate the host to perform maintenance tasks.
Example 14.32. Action to deactivate a host
POST /ovirt-engine/api/hosts/2ab5e1da-b726-4274-bbf7-0a42b16a0fc3/deactivate HTTP/1.1 Accept: application/xml Content-type: application/xml <action/>
14.8.6. Host iSCSI Login Action
The
iscsilogin action enables a host to login to an iSCSI target. Logging into a target makes the contained LUNs available in the host_storage collection.
Example 14.33. Action to enable a host to login to iSCSI target
POST /ovirt-engine/api/hosts/2ab5e1da-b726-4274-bbf7-0a42b16a0fc3/iscsilogin HTTP/1.1
Accept: application/xml
Content-Type: application/xml

<password>s3kr37</password>
</iscsi>
</action>
14.8.7. Host iSCSI Discover Action
The
iscsidiscover action enables an iSCSI portal to be queried for its list of targets.
Example 14.34. Action to query a list of targets for iSCSI portal
POST /ovirt-engine/api/hosts/2ab5e1da-b726-4274-bbf7-0a42b16a0fc3/iscsidiscover HTTP/1.1
Accept: application/xml
Content-Type: application/xml
<action>
<iscsi>
<address>mysan.example.com</address>
<port>3260</port>
</iscsi>
</action>
14.8.8. Commit Host Network Configuration Action
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.
Example 14.35. Action to commit network configuration
POST /ovirt-engine/api/hosts/2ab5e1da-b726-4274-bbf7-0a42b16a0fc3/commitnetconfig HTTP/1.1 Accept: application/xml Content-type: application/xml <action/>
Important
Networking configuration is only committed after the Manager 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.
14.8.9. Setting SPM
Manually set a host as the Storage Pool Manager (SPM).
Example 14.36. Action to Set Host as SPM
POST /ovirt-engine/api/hosts/2ab5e1da-b726-4274-bbf7-0a42b16a0fc3/forceselectspm HTTP/1.1 Accept: application/xml Content-type: application/xml <action/>
