Announcing Incus 6.6

A slightly less busy release this time, mostly due to traveling to the Linux Plumbers Conference and associated events a few weeks ago.

But still far from a boring release. On top of the usual bugfix and performance improvements, we’re getting a number of nice additions for virtual machines, improved clustered LVM support, improvements to incus-migrate and a number of new network features!

The highlights for this release are:

  • OS info for virtual machines
  • Console history for virtual machines
  • Ability to create clustered LVM volume groups
  • QCOW2 and VMDK support in incus-migrate
  • Configurable macvlan mode
  • Load-balancer health information
  • External interfaces in OVN networks
  • Parallel cluster evacuation/restoration

The full announcement and changelog can be found here.
And for those who prefer videos, here’s the release overview video:

And as always, my company is offering commercial support on Incus, ranging from by-the-hour support contracts to one-off services on things like initial migration from LXD, review of your deployment to squeeze the most out of Incus or even feature sponsorship. You’ll find all details of that here: https://zabbly.com/incus

LXC/LXCFS/Incus 6.0.2 LTS release

Introduction

The Linux Containers project maintains Long Term Support (LTS) releases for its core projects.
Those come with 5 years of support from upstream with the first two years including bugfixes, minor improvements and security fixes and the remaining 3 years getting only security fixes.

This is now the second round of bugfix releases for LXC, LXCFS and Incus 6.0 LTS.

LXC

LXC is the oldest Linux Containers project and the basis for almost every other one of our projects.
This low-level container runtime and library was first released in August 2008, led to the creation of projects like Docker and today is still actively used directly or indirectly on millions of systems.

Announcement: https://discuss.linuxcontainers.org/t/lxc-6-0-2-lts-has-been-released/21632

Highlights of this point release:

  • Reduced log level on some common messages
  • Fix compilation error on aarch64

LXCFS

LXCFS is a FUSE filesystem used to workaround some shortcomings of the Linux kernel when it comes to reporting available system resources to processes running in containers.
The project started in late 2014 and is still actively used by Incus today as well as by some Docker and Kubernetes users.

Announcement: https://discuss.linuxcontainers.org/t/lxcfs-6-0-2-lts-has-been-released/21631

Highlights of this point release:

  • Fix building of LXCFS on musl systems (missing include)

Incus

Incus is our most actively developed project. This virtualization platform is just over a year old but has already seen over 3500 commits by over 120 individual contributors. Its first LTS release made it usable in production environments and significantly boosted its user base.

Announcement: https://discuss.linuxcontainers.org/t/incus-6-0-2-lts-has-been-released/21633

Highlights of this point release:

  • Completion of transition to native OVSDB for OVS/OVN
  • Baseline CPU defintiion for clustered users
  • Filesystem support for io.bus and io.cache
  • CPU flags in server resources
  • Unified image support in incus-simplestreams
  • Completion of libovsdb transition
  • Using a sub-path of a volume as a disk
  • Per storage pool projects limits
  • Isolated OVN networks (no uplink)
  • Per-instance LXCFS
  • Support for environment file at create/launch time
  • Instance auto-restart
  • Column selection in all list commands
  • QMP command hooks and scriptlet
  • Live disk resize support in virtual machines
  • PCI devices hotplug
  • OVN load-balancer health checks
  • Promiscuous mode for OVN NICs
  • Ability to run off IP allocation on OVN NICs
  • Customizable OIDC scope request
  • Configurable LVM PV metadata size
  • Configurable OVS socket path

What’s next?

We’re expecting another LTS bugfix release for the 6.0 branches later this year.

On top of that, Q4 of 2024 will also feature non-LTS feature releases of both LXC and LXCFS as we’re trying to push out new releases of those two projects every 6 months now.

Incus will keep going with its usual monthly feature release cadence.

Announcing Incus 6.4

This release builds upon the recently added OCI support from Incus 6.3, making it even easier to run application containers.

The highlights for this release are:

  • Cluster group configuration
  • Per-cluster group CPU baseline
  • Attaching sub-directories of custom storage volumes
  • Per storage pool project limits
  • Isolated OVN networks (no uplink)
  • Per-instance LXCFS

Announcing Incus 6.3

This release includes the long awaited OCI/Docker image support!
With this, users who previously were either running Docker alongside Incus or Docker inside of an Incus container just to run some pretty simple software that’s only distributed as OCI images can now just do it directly in Incus.

In addition to the OCI container support, this release also comes with:

  • Baseline CPU definition within clusters
  • Filesystem support for io.bus and io.cache
  • Improvements to incus top
  • CPU flags in server resources
  • Unified image support in incus-simplestreams
  • Completion of libovsdb transition
