Parameters

Parameter Choices/Defaults Comments
cdrom
dictionary
A CD-ROM configuration for the VM.
All parameters are case sensitive.
Valid parameters are:
- type (string): The type of CD-ROM, valid options are none or iso. With none the CD-ROM device will be present but empty.
- iso_name (string): The file name of an ISO image from one of the XenServer ISO Libraries (implies type: iso). Required if type is set to iso.
custom_params
list
Define a list of custom VM params to set on VM.
Useful for advanced users familiar with managing VM params trough xe CLI.
A custom value object takes two fields key and value (see example below).
disks
list
A list of disks to add to VM.
All parameters are case sensitive.
Removing or detaching existing disks of VM is not supported.
Required parameters per entry:
- size_[tb,gb,mb,kb,b] (integer): Disk storage size in specified unit. VM needs to be shut down to reconfigure this parameter.
Optional parameters per entry:
- name (string): Disk name. You can also use name_label as an alias.
- name_desc (string): Disk description.
- sr (string): Storage Repository to create disk on. If not specified, will use default SR. Cannot be used for moving disk to other SR.
- sr_uuid (string): UUID of a SR to create disk on. Use if SR name is not unique.

aliases: disk
folder
string
Destination folder for VM.
This parameter is case sensitive.
Example:
folder: /folder1/folder2
force
boolean
    Choices:
  • no ←
  • yes
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.
- memory_mb (integer): Amount of memory in MB.
home_server
string
Name of a XenServer host that will be a Home Server for the VM.
This parameter is case sensitive.
hostname
string
Default:
"localhost"
The hostname or IP address of the XenServer host or XenServer pool master.
If the value is not specified in the task, the value of environment variable XENSERVER_HOST will be used instead.

aliases: host, pool
is_template
boolean
    Choices:
  • no ←
  • yes
Convert VM to template.
linked_clone
boolean
    Choices:
  • no ←
  • yes
Whether to create a Linked Clone from the template, existing VM or snapshot. If no, will create a full copy.
This is equivalent to Use storage-level fast disk clone option in XenCenter.
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 uuid to uniquely specify VM to manage.
This parameter is case sensitive.

aliases: name_label
name_desc
string
VM description.
networks
list
A list of networks (in the order of the NICs).
All parameters are case sensitive.
Required parameters per entry:
- name (string): Name of a XenServer network to attach the network interface to. You can also use name_label as an alias.
Optional parameters per entry (used for VM hardware):
- 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
    Choices:
  • present ←
  • absent
  • poweredon
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
    Choices:
  • no
  • yes ←
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
    Choices:
  • no ←
  • yes
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 and 7.2.
  • XenAPI Python library can be acquired from XenServer SDK (downloadable from Citrix website) or by running pip install XenAPI (possibly very old version, not compatible with Python 3.x). Latest version can also be acquired from GitHub: https://raw.githubusercontent.com/xapi-project/xen-api/master/scripts/examples/python/XenAPI.py
  • If no scheme is specified in hostname, module defaults to http:// because https:// is problematic in most setups. Make sure you are accessing XenServer host in trusted environment or use https:// scheme explicitly.
  • To use https:// scheme for hostname you have to either import host certificate to your OS certificate store or use validate_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 and networks.type6 values none and dhcp have same effect. More info here: https://xenserver.org/blog/entry/set-windows-guest-vm-static-ip-address-in-xenserver.html
  • On 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 using xenstore ls and xenstore read tools on *nix guests or trough WMI interface on Windows guests. They can also be found in VM facts instance.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.
