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 Tailscale?

Tailscale ships PAM and an AI gateway in the same week — the network fabric is becoming an enterprise control plane.

Tailscale has pushed two major capability expansions that move it well past its original zero-config VPN positioning. Aperture, a managed gateway for LLM traffic with cost controls, guardrails, MCP support, and session logging, went GA on August 25. Tailscale PAM — privileged access management for SSH, database, RDP, HTTPS, Kubernetes, and S3 — entered beta the following day, including session recording, credential injection, and a browser client that removes the requirement to install Tailscale at all. The core product's v1.102.x maintenance cadence remains steady, addressing a security vulnerability (TS-2026-011) and ongoing Kubernetes operator hardening.

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.

7.5

Tailscale ships PAM and an AI gateway in the same week — the network fabric is becoming an enterprise control plane.

◆ Current state

Tailscale has pushed two major capability expansions that move it well past its original zero-config VPN positioning. Aperture, a managed gateway for LLM traffic with cost controls, guardrails, MCP support, and session logging, went GA on August 25. Tailscale PAM — privileged access management for SSH, database, RDP, HTTPS, Kubernetes, and S3 — entered beta the following day, including session recording, credential injection, and a browser client that removes the requirement to install Tailscale at all. The core product's v1.102.x maintenance cadence remains steady, addressing a security vulnerability (TS-2026-011) and ongoing Kubernetes operator hardening.

◆ Where it's heading

Both product tracks — enterprise access control and AI infrastructure — are running simultaneously, which signals organizational ambition beyond typical infrastructure incrementalism. Tailscale is positioning itself as the secure transport and policy layer for both human and agentic access to resources, with MCP native support as a differentiator no pure AI gateway can replicate. PAM will likely graduate from beta to GA within a few releases, while Aperture's direct token purchasing and audit logging features will be the levers that attract enterprise security teams.

◆ Prediction

Tailscale PAM's GA and deeper SIEM/audit-export integrations are the clearest next move. If Aperture's MCP endpoint gets traction among engineering teams, expect Tailscale to build organization-level policy controls for AI agent access — extending its existing ACL primitives into the LLM call graph.
