The highlights for this release are:
Network address sets
Memory hotplug support in VMs
Reworked logging handling & remote syslog
SNAT support on complex network forwards
Authentication through access_token parameter
Improved server-side filtering in the CLI
More generated documentation

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 fourth 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.
New LXC_IPV6_ENABLE lxc-net configuration key to turn IPv6 on/off
Fixed ability to attach to application containers with non-root entry point
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.
Properly handle SLAB reclaimable memory in meminfo
Handle empty cpuset strings
Fix potential sleep interval overflows
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.
Due to the nature of this tool, it doesn’t get LTS releases as its feature set is extremely stable but still needs to receive very frequent updates to handle changes in the various Linux distributions that it builds. Distrobuilder 3.2 was released at the same time as the LTS releases, providing an up to date snapshot of that project.
systemd generator handles newer Linux distributions
Support for Alpaquita
What’s next?
We’re expecting another LTS bugfix release for the 6.0 branches in the third quarter of 2025. In the mean time, Incus will keep going with its usual monthly feature release cadence.
Thanks
This LTS release update was made possible thanks to funding provided by the Sovereign Tech Fund (now part of the Sovereign Tech Agency).
The Sovereign Tech Fund supports the development, improvement, and maintenance of open digital infrastructure. Its goal is to sustainably strengthen the open source ecosystem, focusing on security, resilience, technological diversity, and the people behind the code.
The Incus team is pleased to announce the release of Incus 6.11!
Without a doubt, the headline feature for this release is initial support for Linstor as a new storage driver for those looking for an alternative to Ceph! But that’s far from all that this Incus release brings to the table. It also comes with a lot of new VM, OCI and networking features!
The highlights for this release are:
Linstor storage driver
New MAC address range
USB NICs in VMs
USB disks in VMs
Tracking of VM machine definition
Configurable OCI entrypoint
Unprivileged ICMP (ping) in OCI containers
Unprivileged low ports in OCI containers
Allocated CPU time in instance state API
Configurable DNS servers
Extra IPv4 routes through DHCP
Configurable IPv4 DHCP lease expiry on OVN
OVN logical switch name now part of network state
