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: U(https://raw.githubusercontent.com/xapi-project/xen-api/master/scripts/examples/python/XenAPI/XenAPI.py)' - 'If no scheme is specified in C(hostname), module defaults to C(http://) because C(https://) is problematic in most setups. Make sure you are accessing XenServer host in trusted environment or use C(https://) scheme explicitly.' - 'To use C(https://) scheme for C(hostname) you have to either import host certificate to your OS certificate store or use C(validate_certs: no) which requires XenAPI library from XenServer 7.2 SDK or newer and Python 2.7.9 or newer.' requirements: - python >= 2.6 - XenAPI attributes: check_mode: support: full diff_mode: support: none options: state: description: - Specify the state VM should be in. - If O(state) is set to value other than V(present), then VM is transitioned into required state and facts are returned. - If O(state) is set to V(present), then VM is just checked for existence and facts are returned. type: str default: present choices: [ powered-on, powered-off, restarted, shutdown-guest, reboot-guest, suspended, present ] name: description: - Name of the VM to manage. - 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 O(uuid) to uniquely specify VM to manage. - This parameter is case sensitive. type: str aliases: [ name_label ] uuid: description: - UUID of the VM to manage if known. This is XenServer's unique identifier. - It is required if name is not unique. type: str wait_for_ip_address: description: - Wait until XenServer detects an IP address for the VM. - This requires XenServer Tools to be preinstalled on the VM to work properly. type: bool default: false state_change_timeout: description: - 'By default, module will wait indefinitely for VM to change state or acquire an IP address if O(wait_for_ip_address=true).' - 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. type: int default: 0 extends_documentation_fragment: - community.general.xenserver.documentation - community.general.attributes ''' EXAMPLES = r''' - name: Power on VM community.general.xenserver_guest_powerstate: hostname: "{{ xenserver_hostname }}" username: "{{ xenserver_username }}" password: "{{ xenserver_password }}" name: testvm_11 state: powered-on delegate_to: localhost register: facts ''' RETURN = r''' instance: description: Metadata about the VM returned: always type: dict sample: { "cdrom": { "type": "none" }, "customization_agent": "native", "disks": [ { "name": "windows-template-testing-0", "name_desc": "", "os_device": "xvda", "size": 42949672960, "sr": "Local storage", "sr_uuid": "0af1245e-bdb0-ba33-1446-57a962ec4075", "vbd_userdevice": "0" }, { "name": "windows-template-testing-1", "name_desc": "", "os_device": "xvdb", "size": 42949672960, "sr": "Local storage", "sr_uuid": "0af1245e-bdb0-ba33-1446-57a962ec4075", "vbd_userdevice": "1" } ], "domid": "56", "folder": "", "hardware": { "memory_mb": 8192, "num_cpu_cores_per_socket": 2, "num_cpus": 4 }, "home_server": "", "is_template": false, "name": "windows-template-testing", "name_desc": "", "networks": [ { "gateway": "192.168.0.254", "gateway6": "fc00::fffe", "ip": "192.168.0.200", "ip6": [ "fe80:0000:0000:0000:e9cb:625a:32c5:c291", "fc00:0000:0000:0000:0000:0000:0000:0001" ], "mac": "ba:91:3a:48:20:76", "mtu": "1500", "name": "Pool-wide network associated with eth1", "netmask": "255.255.255.128", "prefix": "25", "prefix6": "64", "vif_device": "0" } ], "other_config": { "base_template_name": "Windows Server 2016 (64-bit)", "import_task": "OpaqueRef:e43eb71c-45d6-5351-09ff-96e4fb7d0fa5", "install-methods": "cdrom", "instant": "true", "mac_seed": "f83e8d8a-cfdc-b105-b054-ef5cb416b77e" }, "platform": { "acpi": "1", "apic": "true", "cores-per-socket": "2", "device_id": "0002", "hpet": "true", "nx": "true", "pae": "true", "timeoffset": "-25200", "vga": "std", "videoram": "8", "viridian": "true", "viridian_reference_tsc": "true", "viridian_time_ref_count": "true" }, "state": "poweredon", "uuid": "e3c0b2d5-5f05-424e-479c-d3df8b3e7cda", "xenstore_data": { "vm-data": "" } } ''' from ansible.module_utils.basic import AnsibleModule from ansible_collections.community.general.plugins.module_utils.xenserver import (xenserver_common_argument_spec, XenServerObject, get_object_ref, gather_vm_params, gather_vm_facts, set_vm_power_state, wait_for_vm_ip_address) class XenServerVM(XenServerObject): """Class for managing XenServer VM.
