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 >= 4.3.0

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	Choices: no yes	A boolean flag that indicates if the server TLS certificate and host name should be checked.
	kerberos boolean	Choices: 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		Choices: 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 -		Choices: cdrom hd network	List of boot devices which should be used to boot. For example `[ cdrom, hd ]`. Default value is set by oVirt/RHV engine.
cpu_cores -			Number of virtual CPUs cores of the Instance Type. Default value is set by oVirt/RHV engine.
cpu_mode -			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 -			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` - Number of the host CPU. `vcpu` - Number of the instance type CPU.
cpu_sockets -			Number of virtual CPUs sockets of the Instance Type. Default value is set by oVirt/RHV engine.
cpu_threads -			Number of virtual CPUs sockets of the Instance Type. Default value is set by oVirt/RHV engine.
description -			Description of the instance type.
fetch_nested boolean		Choices: no yes	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`.
graphical_console -			Assign graphical console to the instance type. Graphical console is a dictionary which can have following values: `headless_mode` - If true disable the graphics console for this instance type. `protocol` - Graphical protocol, a list of spice, vnc, or both.
high_availability boolean		Choices: no yes	If yes Instance Type will be set as highly available. 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 -			Indicates the priority of the instance type inside the run and migration queues. Instance Type with higher priorities will be started and migrated before instance types with lower priorities. The value is an integer between 0 and 100. The higher the value, the higher the priority. If no value is passed, default value is set by oVirt/RHV engine.
host -			Specify host where Instance Type should be running. By default the host is chosen by engine scheduler. This parameter is used only when `state` is running or present.
id -			ID of the Instance Type to manage.
io_threads -			Number of IO threads used by instance type. 0 means IO threading disabled.
memory -			Amount of memory of the Instance Type. Prefix uses IEC 60027-2 standard (for example 1GiB, 1024MiB). Default value is set by engine.
memory_guaranteed -			Amount of minimal guaranteed memory of the Instance Type. Prefix uses IEC 60027-2 standard (for example 1GiB, 1024MiB). `memory_guaranteed` parameter can't be lower than `memory` parameter. Default value is set by engine.
memory_max -			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). Default value is set by engine.
name -			Name of the Instance Type to manage. If instance type don't exists `name` is required. Otherwise `id` or `name` can be used.
nested_attributes list			Specifies list of the attributes which should be fetched from the API. This parameter apply only when `fetch_nested` is true.
nics -			List of NICs, which should be attached to Virtual Machine. NIC is described by following dictionary. `name` - Name of the NIC. `profile_name` - Profile name where NIC should be attached. `interface` - Type of the network interface. One of following virtio, e1000, rtl8139, default is virtio. `mac_address` - Custom MAC address of the network interface, by default it's obtained from MAC pool. 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_nic module instead.
operating_system -			Operating system of the Instance Type. Default value is set by oVirt/RHV engine. Possible values: debian_7, freebsd, freebsdx64, other, other_linux, other_linux_kernel_4, other_linux_ppc64, other_linux_s390x, other_ppc64, other_s390x, rhcos_x64, rhel_3, rhel_3x64, rhel_4, rhel_4x64, rhel_5, rhel_5x64, rhel_6, rhel_6_9_plus_ppc64, rhel_6_ppc64, rhel_6x64, rhel_7_ppc64, rhel_7_s390x, rhel_7x64, rhel_8x64, rhel_atomic7x64, sles_11, sles_11_ppc64, sles_12_s390x, ubuntu_12_04, ubuntu_12_10, ubuntu_13_04, ubuntu_13_10, ubuntu_14_04, ubuntu_14_04_ppc64, ubuntu_16_04_s390x, windows_10, windows_10x64, windows_2003, windows_2003x64, windows_2008, windows_2008R2x64, windows_2008x64, windows_2012R2x64, windows_2012x64, windows_2016x64, windows_2019x64, windows_7, windows_7x64, windows_8, windows_8x64, windows_xp
placement_policy -			The configuration of the instance type's placement policy. Placement policy can be one of the following values: `migratable` - Allow manual and automatic migration. `pinned` - Do not allow migration. `user_migratable` - Allow manual migration only. If no value is passed, default value is set by oVirt/RHV engine.
poll_interval integer		Default: 3	Number of the seconds the module waits until another poll request on entity status is sent.
rng_bytes -			Number of bytes allowed to consume per period.
rng_device -			Random number generator (RNG). You can choose of one the following devices urandom, random or hwrng. In order to select hwrng, you must have it enabled on cluster first. /dev/urandom is used for cluster version >= 4.1, and /dev/random for cluster version <= 4.0
