Parameters
Parameter | Choices/Defaults | Comments | |
---|---|---|---|
activate boolean added in 2.4 |
|
If This parameter is good to disable, when you don't want to change the state of host when using present | |
address - |
Host address. It can be either FQDN (preferred) or IP address. | ||
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 Default value is set by | ||
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 Either | ||
insecure boolean |
|
A boolean flag that indicates if the server TLS certificate and host name should be checked. | |
kerberos boolean |
|
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 | ||
token string |
Token to be used instead of login with username/password. Default value is set by | ||
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 Either | ||
username string / required |
The name of the user, something like admin@internal. Default value is set by | ||
check_upgrade boolean added in 2.4 |
|
If true and | |
cluster - |
Name of the cluster, where host should be created. | ||
comment - |
Description of the host. | ||
fetch_nested boolean added in 2.3 |
|
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 | |
force boolean |
|
Indicates that the host should be removed even if it is non-responsive, or if it is part of a Gluster Storage cluster and has volume bricks on it. | |
hosted_engine - |
|
If deploy it means this host should deploy also hosted engine components. If undeploy it means this host should un-deploy hosted engine components and this host will not function as part of the High Availability cluster. | |
id - added in 2.8 |
ID of the host to manage. | ||
iscsi - added in 2.4 |
If If | ||
kdump_integration - |
|
Specify if host will have enabled Kdump integration. | |
kernel_params - |
List of kernel boot parameters. Following are most common kernel parameters used for host: Hostdev Passthrough & SR-IOV: intel_iommu=on Nested Virtualization: kvm-intel.nested=1 Unsafe Interrupts: vfio_iommu_type1.allow_unsafe_interrupts=1 PCI Reallocation: pci=realloc
Modifying kernel boot parameters settings can lead to a host boot failure. Please consult the product documentation before doing any changes. Kernel boot parameters changes require host deploy and restart. The host needs to be reinstalled successfully and then to be rebooted for kernel boot parameters to be applied. | ||
name - / required |
Name of the host to manage. | ||
nested_attributes list added in 2.3 |
Specifies list of the attributes which should be fetched from the API. This parameter apply only when | ||
override_display boolean |
|
Override the display address of all VMs on this host with specified address. | |
override_iptables boolean |
|
If True host iptables will be overridden by host deploy script. Note that | |
password - |
Password of the root. It's required in case | ||
poll_interval integer |
Default: 3 |
Number of the seconds the module waits until another poll request on entity status is sent. | |
power_management_enabled boolean added in 2.4 |
|
Enable or disable power management of the host. For more comprehensive setup of PM use | |
public_key boolean |
|
True if the public key should be used to authenticate to host. It's required in case
| |
reboot_after_upgrade boolean added in 2.6 |
|
If true and | |
spm_priority - |
SPM priority of the host. Integer value from 1 to 10, where higher number means higher priority. | ||
state - |
|
State which should a host to be in after successful completion. iscsilogin and iscsidiscover are supported since version 2.4. | |
timeout integer |
Default: 600 |
The amount of time in seconds the module should wait for the host to get into desired state. | |
vgpu_placement - added in 2.8 |
|
If consolidated, each vGPU is placed on the first physical card with available space. This is the default placement, utilizing all available space on the physical cards. If separated, each vGPU is placed on a separate physical card, if possible. This can be useful for improving vGPU performance. | |
wait boolean |

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:
# Add host with username/password supporting SR-IOV.
# Note that override_iptables is false by default in oVirt/RHV:
- ovirt_host:
cluster: Default
name: myhost
address: 10.34.61.145
password: secret
override_iptables: true
kernel_params:
- intel_iommu=on
# Add host using public key
- ovirt_host:
public_key: true
cluster: Default
name: myhost2
address: 10.34.61.145
override_iptables: true
# Deploy hosted engine host
