ovirt_host – Module to manage hosts in oVirt/RHV¶
New in version 2.3.
Requirements¶
The below requirements are needed on the host that executes this module.
- python >= 2.7
- ovirt-engine-sdk-python >= 4.2.4
Parameters¶
Parameter | Choices/Defaults | Comments |
---|---|---|
activate
boolean
added in 2.4 |
|
If
state is present activate the host.This parameter is good to disable, when you don't want to change the state of host when using present
state . |
address
-
|
Host address. It can be either FQDN (preferred) or IP address.
|
|
auth
-
/ required
|
Dictionary with values needed to create HTTP/HTTPS connection to oVirt:
username [required] - The name of the user, something like admin@internal. Default value is set by OVIRT_USERNAME environment variable.password [required] - The password of the user. Default value is set by OVIRT_PASSWORD environment variable.url - 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.hostname - 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.token - Token to be used instead of login with username/password. Default value is set by OVIRT_TOKEN environment variable.insecure - A boolean flag that indicates if the server TLS certificate and host name should be checked.ca_file - 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.kerberos - A boolean flag indicating if Kerberos authentication should be used instead of the default basic authentication.headers - Dictionary of HTTP headers to be added to each API call. |

check_upgrade
boolean
added in 2.4 |

If true and
state is upgraded run check for upgrade action before executing upgrade action. |
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
nested_attributes . |
force
boolean
|
|
If True host will be forcibly moved to desired state.
|
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.
|
iscsi
-
added in 2.4 |
If
state is iscsidiscover it means that the iscsi attribute is being used to discover targetsIf
state is iscsilogin it means that the iscsi attribute is being used to login to the specified targets passed as part of the iscsi attribute |
|
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
Note: 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
-
added in 2.3 |
Specifies list of the attributes which should be fetched from the API.
This parameter apply only when
fetch_nested is true. |
|
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
override_iptables is false by default in oVirt/RHV. |
password
-
|
Password of the root. It's required in case
public_key is set to False. |
|
poll_interval
-
|
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
ovirt_host_pm module. |
public_key
boolean
|
|
True if the public key should be used to authenticate to host.
It's required in case
password is not set.aliases: ssh_public_key |
reboot_after_upgrade
boolean
added in 2.6 |
|
If true and
state is upgraded reboot host after successful upgrade. |
spm_priority
-
|
SPM priority of the host. Integer value from 1 to 10, where higher number means higher priority.

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=4.2.4
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
- ovirt_host:
cluster: Default
name: myhost2
password: secret
address: 10.34.61.145
override_iptables: true
hosted_engine: deploy
