Microsoft Hyper-V

Microsoft Hyper-V is a native hypervisor built into Windows, enabling the creation and management of virtual machines on Windows Server and Windows client editions.

Hyper-V integrates virtual machine, storage, and networking management through the Hyper-V Manager or Windows Admin Center, and supports high availability through Windows Server Failover Clustering (WSFC).

WinCC OA is regularly used and validated on Hyper-V running on Windows 11 Enterprise, Windows Server 2022/2025.

Notes and Restrictions

WinCC OA must be properly shut down before a Virtual Machine is stopped.
An "online backup" ("snapshot") of a Virtual Machine is not supported.
A snapshot of a virtual machine cannot be restored.
The clock of the virtual machine must never make an unexpected jump (forward or backward) while WinCC OA is running.
Redundant WinCC OA systems shall run on physically redundant hardware and network configurations.
