folder
string
|
Destination folder for VM.
This parameter is case sensitive.
Example:
folder: /folder1/folder2
|
|
force
boolean
|
|
Ignore warnings and complete the actions.
This parameter is useful for removing VM in running state or reconfiguring VM params that require VM to be shut down.
|
hardware
dictionary
|
Manage VM's hardware parameters. VM needs to be shut down to reconfigure these parameters.
Valid parameters are:
-
num_cpus (integer): Number of CPUs.-
num_cpu_cores_per_socket (integer): Number of Cores Per Socket. num_cpus has to be a multiple of num_cpu_cores_per_socket .-

is_template
boolean
|
|
Convert VM to template.
|
linked_clone
boolean

name
string
/ required
|
Name of the VM to work with.
VMs running on XenServer do not necessarily have unique names. The module will fail if multiple VMs with same name are found.
In case of multiple VMs with same name, use

-
mac (string): Customize MAC address of the interface.Optional parameters per entry (used for OS customization):
-
type (string): Type of IPv4 assignment, valid options are none , dhcp or static . Value none means whatever is default for OS. On some operating systems it could be DHCP configured (e.g. Windows) or unconfigured interface (e.g. Linux).-
ip (string): Static IPv4 address (implies type: static ). Can include prefix in format <IPv4 address>/<prefix> instead of using netmask .-
netmask (string): Static IPv4 netmask required for ip if prefix is not specified.-
gateway (string): Static IPv4 gateway.-
type6 (string): Type of IPv6 assignment, valid options are none , dhcp or static . Value none means whatever is default for OS. On some operating systems it could be DHCP configured (e.g. Windows) or unconfigured interface (e.g. Linux).-
ip6 (string): Static IPv6 address (implies type6: static ) with prefix in format <IPv6 address>/<prefix>.-
gateway6 (string): Static IPv6 gateway.aliases: network |
|
password
string
|
The password to use for connecting to XenServer.
If the value is not specified in the task, the value of environment variable
XENSERVER_PASSWORD will be used instead.aliases: pass, pwd |
|
state
string
|
|
Specify the state VM should be in.
If
state is set to present and VM exists, ensure the VM configuration conforms to given parameters.If
state is set to present and VM does not exist, then VM is deployed with given parameters.If
state is set to absent and VM exists, then VM is removed with its associated components.If
state is set to poweredon and VM does not exist, then VM is deployed with given parameters and powered on automatically. |
state_change_timeout
integer
|
Default: 0
|
By default, module will wait indefinitely for VM to accquire an IP address if
wait_for_ip_address: yes .If this parameter is set to positive value, the module will instead wait specified number of seconds for the state change.
In case of timeout, module will generate an error message.
|
template
string
|
Name of a template, an existing VM (must be shut down) or a snapshot that should be used to create VM.
Templates/VMs/snapshots on XenServer do not necessarily have unique names. The module will fail if multiple templates with same name are found.
In case of multiple templates/VMs/snapshots with same name, use
template_uuid to uniquely specify source template.If VM already exists, this setting will be ignored.
This parameter is case sensitive.
aliases: template_src |
|
template_uuid
string
|
UUID of a template, an existing VM or a snapshot that should be used to create VM.
It is required if template name is not unique.
|
|
username
string
|
Default: "root"
|
The username to use for connecting to XenServer.
If the value is not specified in the task, the value of environment variable
XENSERVER_USER will be used instead.aliases: admin, user |
uuid
string
|
UUID of the VM to manage if known. This is XenServer's unique identifier.
It is required if name is not unique.
Please note that a supplied UUID will be ignored on VM creation, as XenServer creates the UUID internally.
|
|
validate_certs
boolean
|
|
Allows connection when SSL certificates are not valid. Set to
false when certificates are not trusted.If the value is not specified in the task, the value of environment variable
XENSERVER_VALIDATE_CERTS will be used instead. |
wait_for_ip_address
boolean
|
|
Wait until XenServer detects an IP address for the VM. If
state is set to absent , this parameter is ignored.This requires XenServer Tools to be preinstalled on the VM to work properly.
|
Notes¶
Note
Minimal supported version of XenServer is 5.6.
Module was tested with XenServer 6.5, 7.1, 7.2, 7.6, Citrix Hypervisor 8.0, XCP-ng 7.6 and 8.0.
To acquire XenAPI Python library, just run
pip install XenAPI
on your Ansible Control Node. The library can also be found inside Citrix Hypervisor/XenServer SDK (downloadable from Citrix website). Copy the XenAPI.py file from the SDK to your Python site-packages on your Ansible Control Node to use it. Latest version of the library can also be acquired from GitHub: https://raw.githubusercontent.com/xapi-project/xen-api/master/scripts/examples/python/XenAPI.pyIf no scheme is specified in
hostname
, module defaults tohttp://
becausehttps://
is problematic in most setups. Make sure you are accessing XenServer host in trusted environment or usehttps://
scheme explicitly.To use
https://
scheme forhostname
you have to either import host certificate to your OS certificate store or usevalidate_certs: no
which requires XenAPI library from XenServer 7.2 SDK or newer and Python 2.7.9 or newer.Network configuration inside a guest OS, by using
networks.type
,networks.ip
,networks.gateway
etc. parameters, is supported on XenServer 7.0 or newer for Windows guests by using official XenServer Guest agent support for network configuration. The module will try to detect if such support is available and utilize it, else it will use a custom method of configuration via xenstore. Since XenServer Guest agent only support None and Static types of network configuration, where None means DHCP configured interface,networks.type
andnetworks.type6
valuesnone
anddhcp
have same effect. More info here: https://www.citrix.com/community/citrix-developer/citrix-hypervisor-developer/citrix-hypervisor-developing-products/citrix-hypervisor-staticip.htmlOn platforms without official support for network configuration inside a guest OS, network parameters will be written to xenstore
vm-data/networks/<vif_device>
key. Parameters can be inspected by usingxenstore ls
andxenstore read
tools on *nix guests or trough WMI interface on Windows guests. They can also be found in VM factsinstance.xenstore_data
key as returned by the module. It is up to the user to implement a boot time scripts or custom agent that will read the parameters from xenstore and configure network with given parameters. Take note that for xenstore data to become available inside a guest, a VM restart is needed hence module will require VM restart if any parameter is changed. This is a limitation of XenAPI and xenstore. Considering these limitations, network configuration trough xenstore is most useful for bootstraping newly deployed VMs, much less for reconfiguring existing ones.
