Nutanix closed out 2025 with a major coordinated platform release across AHV, AOS, Prism Central, and Nutanix Guest Tools (NGT). While each component brings its own enhancements, the real story is how these releases come together to improve operational consistency, security, scalability, and flexibility across Nutanix environments.
This post highlights the most impactful updates across all four releases and why they matter for day-to-day operations and long-term platform design.
AHV 11.0: Modern Hypervisor Foundations. AHV 11.0 is a major hypervisor release focused on hardware compatibility, modernized networking, and operational flexibility.
- Expanded CPU Compatibility: AHV now supports AMD Milan and AMD Genoa processors for Advanced Processor Compatibility (APC). This is particularly important for environments that standardize across mixed CPU generations or plan hardware refreshes without sacrificing VM mobility.
- IPv6 Support for AHV Hosts: AHV hosts can now operate in dual-stack IPv4/IPv6 mode, enabling IPv6 connectivity to external services such as DNS, NTP, and syslog. This aligns AHV with broader data center IPv6 adoption strategies and removes a long-standing infrastructure gap.
- AHV Installer for Compute-Only Nodes: The AHV Installer enables AHV deployment on compute-only nodes without requiring Nutanix Foundation imaging. This is a key enabler for:
- Compute-only clusters
- External storage integrations
- Disaggregated architectures
- Elastic VM Storage (Shared with AOS & PC): AHV 11.0 participates in the new Elastic VM Storage capability, allowing VMs to consume storage from a remote AHV cluster within the same Prism Central domain.
AOS 7.5: Storage, Security, and Resiliency at Scale: AOS 7.5 is a feature-rich release that touches nearly every layer of the Nutanix storage and data services stack.
- Autonomous Extent Store (AES) Everywhere: This delivers reduced CPU overhead, improved metadata locality, and sustained write performance without requiring operational changes.
- Default for all new all-flash deployments
- Automatically enabled for qualifying hybrid clusters during upgrade
- Erasure Coding Efficiency Improvements: AOS 7.5 dramatically improves garbage collection and stripe optimization for erasure-coded data, resulting in:
- Faster space reclamation
- More predictable capacity recovery
- Better performance in high-churn environments
- Higher Capacity All-Flash Nodes: Existing all-flash nodes can now be upgraded to 185 TB per node, improving storage density while maintaining Nutanix’s enterprise DR capabilities.
- Enhanced CVM Security (Now for Upgrades Too): Previously limited to fresh installs, CVM data-access hardening is now applied during upgrades as well — a significant security milestone that strengthens ransomware resistance.
- vTPM Integration with External KMS: Virtual TPM keys can now be protected by a third-party KMS, aligning VM-level encryption with centralized enterprise key management.
- External Storage Momentum: AOS 7.5 expands Nutanix’s external storage strategy with:
- Pure Storage FlashArray support with NVMe-oF/TCP
- Async DR and backup support for Pure-backed deployments
- Improved UI placement and management of external storage resources
Prism Central 7.5: Control Plane Maturity: Prism Central 7.5 is arguably the most expansive release in this cycle, with improvements spanning DR, security, lifecycle operations, observability, and scalability.
- VM Startup Policies: Administrators can now define VM and application startup order during HA events and cluster restarts, a long-requested feature for tiered applications.
- Unified Allocation & Consumption View: A new centralized view shows how CPU, memory, and storage are allocated and consumed across all Prism Central services, improving capacity planning and troubleshooting.
- Cluster Health Checks in Prism Central: NCC is now available directly from the Prism Central UI, allowing operators to monitor multiple clusters without logging into each Prism Element instance.
- Disaster Recovery Capabilities Expanded: Prism Central 7.5 significantly expands native DR functionality, including:
- Multisite replication (1→2 and 1→3 topologies)
- IPv6 support for DR workflows
- Reverse replication control after failover
- Protection scaling up to 10,000 entities
- Elastic VM Storage Management: The control plane for Elastic VM Storage resides in Prism Central, enabling cross-cluster storage consumption at scale.
- External KMS Support in Prism Central: Centralized KMS configuration now supports both:
- Cluster encryption
- vTPM key protection
- IAM Improvements: User deactivation, UX enhancements, and WCAG 2.2 accessibility improvements make identity management cleaner and more enterprise-friendly.
Nutanix Guest Tools (NGT) 4.5: Guest-Level Consistency: NGT 4.5 may appear narrower in scope, but it plays a critical role in guest lifecycle automation and visibility.
- Reusable Guest Customization Profiles: NGT 4.5 enables reusable Windows guest customization profiles that integrate with:
- VM cloning
- VM templates
- Prism Central workflows
- Automatic NGT Configuration on Cloned VMs: Cloned VMs now inherit NGT configuration automatically, reducing post-clone manual steps and configuration drift.
- Improved Visibility in Prism Central: Administrators can now view detailed guest information, including OS type/version, DNS name, uptime, and VirtIO version, directly from the VM list view
- Scale Improvements: NGT operations now scale to 2,048 VMs per cluster, aligning with large-scale enterprise and service provider environments.
Summary: What stands out in this release cycle is not any single feature, but the alignment across the entire Nutanix stack:
- AHV modernizes the hypervisor and enables disaggregated designs
- AOS strengthens storage efficiency, security, and external integrations
- Prism Central matures more in the enterprise control plane
- NGT closes the loop at the guest OS layer
Taken together, AHV 11.0, AOS 7.5, Prism Central 7.5, and NGT 4.5 represent a cohesive step forward in Nutanix’s strategy: fewer operational silos, stronger security by default, and more flexibility without added complexity.
If you’re planning a platform upgrade in 2026, this release train is absolutely worth a close look.
