MicroCloud 2.1.1 LTS has been released

jpelizaeus · July 28, 2025, 10:36am

Introduction

The LXD team would like to announce the release of MicroCloud 2.1.1 LTS!

This is the first bugfix release for MicroCloud 2.1. It features an enhanced user interface, more in-depth tests, improved documentation and fixes several bugs around disk selection and re-using of existing MicroCeph clusters.

MicroCloud 2.1 LTS relies on LXD 5.21, MicroCeph Squid, and MicroOVN 24.04 LTS versions. To be able to stay on track with the latest developments of LXD, MicroCloud now also allows using LXD’s latest feature release track 6 for non-production deployments.

As with all our other LTS releases, this one will be supported for 5 years (until June 2029).

Thank you to everyone who contributed to this release!

Release highlights

Enhanced user interface

To provide more precise feedback to the user, we have extended the formatting and coloring of the CLI’s output which was already present for the new microcloud status
command introduced in the last release.
Colors are now used throughout the entire interactive questionnaire to highlight user inputs, actions items, warnings and errors.
This makes it easy to spot configuration or system errors and allows to stay focused throughout the process.

More in-depth tests

As part of making the MicroCloud 2.1 release more stable, a new set of end to end tests was added which allows validating a MicroCloud deployment post installation.
The tests deploy workload (using Terraform) and evacuate, reboot and restore individual machines of the MicroCloud to validate their uptime and connectivity.
Those tests are now running by default in our test pipeline but can also be used to validate any MicroCloud deployment. See the docs for more information.

Improved documentation

The entire set of documentation is now rewritten to use US english.

Additional guides for pre-deployment requirements as well as improvements to MicroCloud’s networking approach have been added.
This makes it easier to reason about MicroCloud’s needs when it comes to the planning of a new deployment.

Furthermore new how-tos were added for properly shutting down a MicroCloud cluster member as well as the correct management and update of the respective snaps.

Support for LXD’s feature release track 6

To experience the latest features introduced in LXD’s feature release track 6, MicroCloud now has the ability to be deployed together with the latest version of LXD. Whilst this is only recommended for non-production deployments, users can already experience new features before they end up in LXD’s next LTS release.
A list of features present in the latest LXD feature release can be seen here.

Bugfix highlights

Stateful migration by default

MicroCloud now sets the instances.migration.stateful=true LXD config setting for new installations.
This ensures that by default instances are migrated statefully.

Exclude already used disks

When using microcloud add, disks which have already been configured for the remote storage pool were still displayed.
As MicroCloud knows which disks are already in use, they are now excluded from the interactive questionnaire when rendering the disk selection tables.

Allow adding existing MicroCeph clusters without configuring new disks

MicroCloud allows to add existing MicroCeph clusters to any MicroCloud deployment.
When doing so, a user usually wants to also configure the remote storage pool in order to make use of the MicroCeph cluster by using the storage pool when creating resources in LXD.

An existing MicroCeph cluster can be added either via microcloud service add or through the microcloud add command.
The latter always required to add a new disks to MicroCeph in order to configure the existing cluster for the remote (distributed) storage pool. If no additional disks was selected, the configuration of the remote storage pool was skipped.

Now the selection of an additional disk is optional and the MicroCeph cluster can just be included in MicroCloud with both commands. An additional information message is printed for the disks which are already configured in MicroCeph.

Profile replacement

In case a new storage pool or network gets added to MicroCloud post installation, the user is prompted whether or not LXD’s default profile should be modified to include the most recent resource instead.
This prompt was only coming up for networks and was skipped for storage pools.

Updating to the new version

In case you are already tracking MicroCloud 2.1 LTS, follow the How to update MicroCloud guide to update your MicroCloud to the latest version 2.1.1.

We recommend that all current users upgrade to the LTS version so that they can benefit from the long term support. The previous version, MicroCloud 1.1 has reached EOL in April 2025.

See the how to upgrade guide.

MicroCloud 2.1.1 LTS is currently available in the 2/candidate snap channel for consideration, and will be moved to the 2/stable channel soon.

jpelizaeus · August 4, 2025, 8:55am

The release has been promoted to the 2/stable channel now.

Following up on our announcement from march, we have also closed both the latest/candidate and latest/stable channels.

aahh finally seeing the new logo on customer deployments!

really looking forward to being able to get some features from lxd into microcloud LTS version, with the lxd feature release track support.

great job team!
