Deploy VMs using Ansible

jedimarcus

bvitnik I can confirm the most simple of tasks where I used your module to create a new VM based on an existing template.

I'm still figuring out how to use this best.

Does setting an IP work on any template (e.g. Linux Ubuntu) with XenTools installed?

jedimarcus Network configuration (IP, subnet, gateway) only works for Windows guests because there is proper support for it in XenServer Guest Tools for Windows. There is no such support (as far as I know) in XenServer Guest Tools for *nix based systems. Unlike tools for Windows, tools for *nix based systems only contain a few xenstore tools and a daemon (xe-daemon) that collects OS metrics. There is no management agent.

My idea is to write a proper agent for *nix based systems at some point but it won't be any time soon. Maybe Citrix (or Vates ?) will implement one before I do.

For now, you can use custom based network configuration trough xenstore and custom scripts. It's described in Notes section of the module documentation.

Hello all,

I try to create a playbook to deploy a Windows Server 2016 VM.
I see a lot of examples with this parameter : register: deploy.
But there is no reference in the parameters guide. Maybe a mistake ?

bvitnik

Ced76 "register" is not a module parameter. It's Ansible task parameter. Take a look at Ansible documentation for registered variables:

https://docs.ansible.com/ansible/latest/user_guide/playbooks_variables.html#registering-variables

Basically what "register: deploy" does is that is says "define a variable called deploy and put a return value of the module in it". A return value of the module in this case are numerous VM facts you can find in "deploy.instance" (sub)variable. Registered variable is accessible in any subsequent task of the same play. Also "deploy" here is just a random name chosen. You can name your registered variables however you like.

bvitnik Understood. Sorry but i'm newbie on Ansible Doesn't see that this variable was not in the xenxerver_guest module part.
I try to create a lab with these objectives :
1- Provision Windows Server 2016 VMs on XCP-NG (or XenServer) after building my own Windows Server 2016 template (using best practices)
2- Define some roles on these VMs (Active Directory, IIS, SQL Server etc.)

Hope it'll be possible ...

Thanks.

Hi all,

Working perfect ! I've deployed 4 VMs from a custom WS2016 template under XCP-NG (version 7.5)
