Incus vs Kubernetes
A side-by-side editorial comparison of Incus and Kubernetes — release velocity, themes, recent moves, and the top alternatives to consider.
Incus vs Kubernetes: at a glance
What is Incus?
Incus 7.4 turns a year of migration plumbing into near-live migration that actually moves disks.
7.0.0 LTS became the supported baseline in May with 7.0.1 as its first patch, while the feature branch kept a roughly monthly cadence: 7.1 cleaned up issues the LTS surfaced, 7.2 added migration-compatible hypervisor flags for stateful migration, 7.3 shipped native Windows and macOS installers. 7.4 is the largest of them and the first with a headline capability — near-live migration implemented on both client and server, extended to dependent disks inside a cluster, with incremental memory migration made opt-in. Alongside it sit Secure Boot key management, a substantial NVRAM rework, librbd for all Ceph interactions, and disk and NIC burst limits.
What is Kubernetes?
Kubernetes v1.37 graduates AI/ML workload support and security hardening to beta and GA.
Kubernetes v1.37 is a broad maturity release, advancing a cohort of v1.35–v1.36 alpha features to beta or GA. Memory QoS is now enabled by default on cgroup v2 nodes, rootless kubelet mode reached beta, and DRA Extended Resource support hit GA — a significant milestone for GPU and accelerator-heavy clusters. The release is stable and forward-moving without architectural pivots.

Incus 7.4 turns a year of migration plumbing into near-live migration that actually moves disks.
◆ Current state
7.0.0 LTS became the supported baseline in May with 7.0.1 as its first patch, while the feature branch kept a roughly monthly cadence: 7.1 cleaned up issues the LTS surfaced, 7.2 added migration-compatible hypervisor flags for stateful migration, 7.3 shipped native Windows and macOS installers. 7.4 is the largest of them and the first with a headline capability — near-live migration implemented on both client and server, extended to dependent disks inside a cluster, with incremental memory migration made opt-in. Alongside it sit Secure Boot key management, a substantial NVRAM rework, librbd for all Ceph interactions, and disk and NIC burst limits.
◆ Where it's heading
Migration has been the through-line for three releases and 7.4 is where it becomes a feature rather than plumbing. The pattern is consistent: 7.2 made stateful migration survive non-identical hosts, 7.4 makes moving an instance cheap enough to do routinely, including the storage that hangs off it. Around that, the VM side is maturing toward parity with commercial hypervisors — firmware key management, NVRAM control, per-device rate limits — which is the surface that decides whether Incus is usable as a datacentre hypervisor rather than a container manager that also runs VMs.
◆ Prediction
Expect the next release to harden near-live migration rather than replace it — the evacuation and cluster-recovery fixes already threaded through 7.4 suggest the gaps are in cluster-wide orchestration, not the transfer itself.
Kubernetes

Kubernetes v1.37 graduates AI/ML workload support and security hardening to beta and GA.
◆ Current state
Kubernetes v1.37 is a broad maturity release, advancing a cohort of v1.35–v1.36 alpha features to beta or GA. Memory QoS is now enabled by default on cgroup v2 nodes, rootless kubelet mode reached beta, and DRA Extended Resource support hit GA — a significant milestone for GPU and accelerator-heavy clusters. The release is stable and forward-moving without architectural pivots.
◆ Where it's heading
The v1.37 cycle signals a clear direction: Kubernetes is building deeper infrastructure for AI/ML and batch workloads, with workload-aware scheduling enhancements, pod-level resource managers, and DRA GA all targeting heterogeneous hardware clusters. Security hardening via rootless mode and storage bind mount controls is a parallel thread. Expect v1.38 to graduate the alpha features from this cycle — scheduler preemption for in-place resize, node lifecycle conditions — while expanding DRA device plugin migration.
◆ Prediction
The most likely next move is pod-level resource managers graduating to stable and broader DRA adoption incentivized by device plugin deprecation pressure. Workload-aware scheduling for AI/ML will continue adding gang-scheduling and topology-aware primitives.
