What are the new virtualization features in Windows Server 2025?

Windows Server 2025 introduces several new virtualization features to enhance performance, scalability, and manageability. Here are some key virtualization features:

• GPU Partitioning (GPU-P): Windows Server 2025 introduces GPU partitioning, allowing administrators to partition GPUs and assign them to virtual machines (VMs). This feature supports high availability and live migration, making it ideal for scenarios requiring GPU resources.
• Accelerated Networking (AccelNet): This feature simplifies the management of single root I/O virtualization (SR-IOV) for VMs hosted on Windows Server 2025 clusters. It uses the high-performance SR-IOV data path to reduce latency, jitter, and CPU utilization.
• Cluster-Aware Updating Enhancements: Windows Server 2025 includes enhancements to cluster-aware updating, improving reliability and performance. It now supports cert-based VM live migration without domain join and GPU-P VM live migration on a failover cluster.
• Hotpatching: Enabled by Azure Arc, hotpatching allows for security updates with fewer reboots and minimal disruption to operations. This feature is available for Azure Arc-enabled Windows Server 2025 Standard or Datacenter running on physical machines, VMs, on-premises, or multicloud servers.
• Workgroup Clusters: Windows Server 2025 introduces workgroup clusters, allowing for cert-based VM live migration without the need for domain join. This feature simplifies the deployment and management of clusters in workgroup environments.
• Improved Storage Replica Performance: Enhancements to Storage Replica improve performance and support stretch clusters between two sites, providing better disaster recovery and high availability
