我昨天从Ansible入手，尝试在我的私有XenServer上配置虚拟机。Ansible Xen Provisioning
我跟着这个指南： XenGuide Sharknet.us
所以我可以从一个ansible平中游Xen的服务器。
我的项目文件夹的结构如下：
Project Folder
|-- site.yml
|-- hosts (inventory file)
+-+ host_vars
| |-- master01.lab.local
| |-- master02.lab.local
| |-- slave01.lab.local
| |-- slave02.lab.local
+-+ group_vars
| |-- all
+-+ roles
| +-+ master
| | |-- main.yml
| +-+ slave
| | |-- main.yml
| +-+ vm
| | |-- create_vm.yml
| | |-- main.yml
我的文件Site.yml：
[vm]
master01.lab.local
master02.lab.local
slave01.lab.local
slave02.lab.local
[hypervisor]
xen01.lab.local
host_vars/master01.lab.local为例：
hostname: master01
ram: 8GiB
vcpus: 4
groups_vars /全部文件：
centos_template_uid: 11fd3dc9-96cc-49af-b091-a2ca7e94c589
primary_sr_uid: 6e074a6e-bf19-031d-7c65-c9ab2749a3da

角色/ VM/main.yml

delegate_to: xen01.lab.local
- include: create_vm.yml
when: found.stdout == ""

register: disk
delegate_to: xen01.lab.local
- name: Assign storage to VM

delegate_to: xen01.lab.local
- name: Launch the VM
command: xe vm-start uuid={{ vm.stdout }}
delegate_to: xen01.lab.local
如果我现在运行以下命令：
ansible-playbook -i hosts site.yml -K
我得到的以下错误：
ERROR! Syntax Error while loading YAML.
The error appears to have been in '/var/ansible/ansible-playbooks/provisioning/xen/roles/vm/tasks/main.yml': line 2, column 1, but may
be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:
- name: Check if VM exists
command: xe vm-list name-label={{ hostname }}
^ here
We could be wrong, but this one looks like it might be an issue with
missing quotes. Always quote template expression brackets when they
start a value. For instance:
with_items:
- {{ foo }}
Should be written as:
with_items:
- "{{ foo }}"
有人知道这个错误吗？
