Synopsis

  • This module manages whole lifecycle of the Instance Type in oVirt/RHV.

Requirements

The below requirements are needed on the host that executes this module.

  • python >= 2.7
  • ovirt-engine-sdk-python >= 4.4.0

Parameters

Parameter Choices/Defaults Comments

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 ca_file parameter is not set, system wide CA certificate store is used.

Default value is set by OVIRT_CAFILE environment variable.

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 OVIRT_HOSTNAME environment variable.

Either url or hostname is required.

insecure

boolean

  • no
  • yes

A boolean flag that indicates if the server TLS certificate and host name should be checked.

kerberos

boolean

  • no
  • yes

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 OVIRT_PASSWORD environment variable.

token

string

Token to be used instead of login with username/password.

Default value is set by OVIRT_TOKEN environment variable.

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 OVIRT_URL environment variable.

Either url or hostname is required.

username

string / required

The name of the user, something like admin@internal.

Default value is set by OVIRT_USERNAME environment variable.

ballooning_enabled

boolean

  • no
  • yes

If true, use memory ballooning.

Memory balloon is a guest device, which may be used to re-distribute / reclaim the host memory based on instance type needs in a dynamic way. In this way it's possible to create memory over commitment states.

boot_devices

list / elements=string

integer

Number of virtual CPUs cores of the Instance Type.

Default value is set by oVirt/RHV engine.

cpu_mode

string

CPU mode of the instance type. It can be some of the following: host_passthrough, host_model or custom.

For host_passthrough CPU type you need to set placement_policy to pinned.

If no value is passed, default value is set by oVirt/RHV engine.

cpu_pinning

list / elements=dictionary

CPU Pinning topology to map instance type CPU to host CPU.

CPU Pinning topology is a list of dictionary which can have following values:

cpu

string

Number of the host CPU.

vcpu

string

Number of the instance type CPU.

cpu_sockets

integer

Number of virtual CPUs sockets of the Instance Type.

Default value is set by oVirt/RHV engine.

If no Instance Type won't be set as highly available.

If no value is passed, default value is set by oVirt/RHV engine.

high_availability_priority

memory_guaranteed parameter can't be lower than memory parameter.

Default value is set by engine.

memory_max

string

Upper bound of instance type memory up to which memory hot-plug can be performed. Prefix uses IEC 60027-2 standard (for example 1GiB, 1024MiB).

This parameter apply only when fetch_nested is true.

nics

list / elements=dictionary

List of NICs, which should be attached to Virtual Machine. NIC is described by following dictionary.

NOTE - This parameter is used only when state is running or present and is able to only create NICs. To manage NICs of the instance type in more depth please use ovirt.ovirt.ovirt_nic module instead.

    rng_period: 200
    soundcard_enabled: true
    virtio_scsi: true
    boot_devices:
      - network

# Remove instance type
- ovirt.ovirt.ovirt_instance_type:
    state: absent
    name: myit


# Create instance type with predefined memory and cpu limits.
- ovirt.ovirt.ovirt_instance_type:
    state: present
    name: myit
    memory: 2GiB
    cpu_cores: 2
    cpu_sockets: 2
    nics:
      - name: nic1

# Enable usb support and serial console
- ovirt.ovirt.ovirt_instance_type:
    name: myit
    usb_support: True
    serial_console: True

# Use graphical console with spice and vnc
- name: Create a instance type that has the console configured for both Spice and VNC
  ovirt.ovirt.ovirt_instance_type:
    name: myit
    graphical_console:
      protocol:
        - spice
        - vnc
