Xen Orchestra Cloud Controller Manager in development

Hello everyone

We publish a development version of a Xen Orchestra Cloud Controller Manager!

It support the controllers cloud-node and cloud-node-lifecycle and add labels to your Kubernetes nodes hosted on Xen Orchestra VMs.

apiVersion: v1
kind: Node
metadata:
  labels:
    # Type generated base on CPU and RAM
    node.kubernetes.io/instance-type: 2VCPU-1GB
    # Xen Orchestra Pool ID of the node VM Host
    topology.kubernetes.io/region: 3679fe1a-d058-4055-b800-d30e1bd2af48
    # Xen Orchestra ID of the node VM Host
    topology.kubernetes.io/zone: 3d6764fe-dc88-42bf-9147-c87d54a73f21
    # Additional labels based on Xen Orchestra data (beta)
    topology.k8s.xenorchestra/host_id: 3d6764fe-dc88-42bf-9147-c87d54a73f21
    topology.k8s.xenorchestra/pool_id: 3679fe1a-d058-4055-b800-d30e1bd2af48
    vm.k8s.xenorchestra/name_label: cgn-microk8s-recipe---Control-Plane
    ...
  name: worker-1
spec:
  ...
  # providerID - magic string:
  #   xeorchestra://{Pool ID}/{VM ID}
  providerID: xeorchestra://3679fe1a-d058-4055-b800-d30e1bd2af48/8f0d32f8-3ce5-487f-9793-431bab66c115

For now, we have only tested the provider with Microk8s.

What's next?

We will test the CCM with other types of Kubernetes clusters and work on fixing known issues.
Also a modification of the XOA Hub recipe will come to include the CCM.
More label will be added (Pool Name, VM Name, etc.).

Feedback is welcome!

You can install and test the XO CCM, and provide feedback to help improve and speed up the release of the first stable version. This is greatly appreciated

Hello there,

We release a new version Terraform provider with improvements of the VM disk lifecycle!

Now you can expand a VM disk with Terraform without data loss.

Read the release note: https://github.com/vatesfr/terraform-provider-xenorchestra/releases/tag/v0.32.0

These two bugs have been fixed in the latest release

Whoo this looks very nice! Thank you for sharing this tool with us!

The release v0.35.0 improves the logging of both the Xen Orchestra golang SDK and the Terraform Provider.

Now it should be easier to read the log using TF_LOG_PROVIDER=DEBUG (see the provider documentation)

Terraform Provider - Release 0.35.1

The new version fixes bugs when creating a VM from a template #361:

• All existing disks in the template are used if they are declared in the TF plan.
• All unused disks in the template are deleted to avoid inconsistency between the TF plan and the actual state.
• It is no longer possible to resize existing template disks to a smaller size (fixes potential source of data loss).

The release: https://github.com/vatesfr/terraform-provider-xenorchestra/releases/tag/v0.35.1

Release v2.2.0

This new version introduces a new field, 'memory_min', for the VM resource and makes a slight change to the 'memory_max' field, which now sets both the dynamic and static maximum memory limits and providing better control of VM memory.

@sid I made that request a while ago, and tried to look into myself too, but the current API of XenOrchestra just doesn't support it, there are many pieces missing from what I could see. I hope with XenOrchestra 6 the API wil support it though.

That's the point. We started working on it, but it wasn't possible to implement the required functionality in the TF provider using the current JRPC API. We are working with the XO team to provide feedback to make it happen with the REST API. I hope the backup resource will be available with XO6

NB: If you want to take a look, there are branches on the GitHub repository. These are for both the provider and the Golang client.

Hi @afk!
We are working on a new version of the Xen Orchestra Terraform provider to improve VM memory control.

In this new version, the memory_max setting will now set the maximum limits for both the dynamic and static memory.

There is also an optional new setting called 'memory_min', which can be used to set the minimum limit for dynamic VM memory.
This version will also resolve the issue with template memory limits used during VM creation.

Can you test this pre-release version and provide us with some feedback? Or maybe just tell us if this new behaviour is more likely to meet your needs?

https://github.com/vatesfr/terraform-provider-xenorchestra/releases/tag/v0.33.0-alpha.1

I will try asap to do a pre-release version for the Pulumi provider.

I created a GitHub issue to track this feature request: https://github.com/vatesfr/terraform-provider-xenorchestra/issues/378

gCyrille created this issue in vatesfr/terraform-provider-xenorchestra

open CPU topology (sockets/cores) for new VMs deployed via Terraform #378

Hi, thank you for the example! We will take a look. It could be a good idea to have a dedicated documentation/web page with usage examples of 'DevOps' tools
