ovirt_hosts - Module to manage hosts in oVirt/RHV
New in version 2.3.
Synopsis
- Module to manage hosts in oVirt/RHV
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 (added in 2.4) | Default: yes | 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 [required] - A string containing the base URL of the server, usually something like `https://server.example.com/ovirt-engine/api`. Default value is set by OVIRT_URL environment variable.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 (added in 2.4) | Default: yes | 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 (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 | Default: no | 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 suceesfully 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 | Override the display address of all VMs on this host with specified address. | |
override_iptables | 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 (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 | Default: no |
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 |
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 | Default: 180 | The amount of time in seconds the module should wait for the instance to get into desired state. |
wait |
True 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=4.0.0
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_hosts: 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_hosts: public_key: true cluster: Default name: myhost2 address: 10.34.61.145 override_iptables: true # Deploy hosted engine host - ovirt_hosts: cluster: Default name: myhost2 password: secret address: 10.34.61.145 override_iptables: true hosted_engine: deploy # Maintenance - ovirt_hosts: state: maintenance name: myhost # Restart host using power management: - ovirt_hosts: state: restarted name: myhost # Upgrade host - ovirt_hosts: state: upgraded name: myhost # discover iscsi targets - ovirt_hosts: state: iscsidiscover name: myhost iscsi: username: iscsi_user password: secret address: 10.34.61.145 port: 3260 # login to iscsi targets - ovirt_hosts: state: iscsilogin name: myhost iscsi: username: iscsi_user password: secret address: 10.34.61.145 target: "iqn.2015-07.com.mlipchuk2.redhat:444" port: 3260 # Reinstall host using public key - ovirt_hosts: state: reinstalled name: myhost public_key: true # Remove host - ovirt_hosts: state: absent name: myhost force: True
Return Values
Common return values are documented here, the following are the fields unique to this module:
Key | Returned | Description |
---|---|---|
host dict | On success if host is found. | Dictionary of all the host attributes. Host attributes can be found on your oVirt/RHV instance at following url: http://ovirt.github.io/ovirt-engine-api-model/master/#types/host. |
id str | On success if host is found. | ID of the host which is managed Sample: 7de90f31-222c-436c-a1ca-7e655bd5b60c |
iscsi_targets list | On success if host is found and state is iscsidiscover. | List of host iscsi targets |
Status
This module is flagged as preview which means that it is not guaranteed to have a backwards compatible interface.
