root_passwordelement that refers to the password for the host'srootuser. - Red Hat Enterprise Virtualization Hypervisor host - This host type requires an
imageelement that refers to an ISO file stored on the Red Hat Enterprise Virtualization Manager server.

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 Enterprise Virtualization Manager. If the connectivity is lost, Red Hat Enterprise 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 14.32. Action to fence a host
POST /api/hosts/2ab5e1da-b726-4274-bbf7-0a42b16a0fc3/fence
Accept: application/xml
Content-Type: application/xml
<action>

POST /api/hosts/2ab5e1da-b726-4274-bbf7-0a42b16a0fc3/deactivate HTTP/1.1 Accept: application/xml Content-type: application/xml <action/>
14.8.6. Approve Host Action
Approve a pre-installed Red Hat Enterprise Virtualization Hypervisor host for usage in the virtualization environment. This action also accepts an optional
cluster element to define the target cluster for this host.
Example 14.34. Action to approve a host
POST /api/hosts/2ab5e1da-b726-4274-bbf7-0a42b16a0fc3/approve HTTP/1.1
Accept: application/xml

</action>
14.8.7. 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 14.35. Action to enable a host to login to iSCSI target
POST /api/hosts/2ab5e1da-b726-4274-bbf7-0a42b16a0fc3/iscsilogin HTTP/1.1
Accept: application/xml

<username>jimmy</username>
<password>s3kr37</password>
</iscsi>
</action>
14.8.8. Host iSCSI Discover Action
The
iscsidiscover action enables an iSCSI portal to be queried for its list of targets.
Example 14.36. Action to query a list of targets for iSCSI portal
POST /api/hosts/2ab5e1da-b726-4274-bbf7-0a42b16a0fc3/iscsidiscover HTTP/1.1
Accept: application/xml

14.8.9. 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 14.37. Action to commit network configuration
POST /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.
14.8.10. Setting SPM
Manually set a host as the Storage Pool Manager (SPM).
Example 14.38. Action to Set Host as SPM
POST /api/hosts/2ab5e1da-b726-4274-bbf7-0a42b16a0fc3/forceselectspm HTTP/1.1 Accept: application/xml Content-type: application/xml <action/>
