Windows Server 2025 Failover Cluster Live Migration Issue
Hi Everyone, I am facing an issue in a Hyper-V Failover Cluster environment where Live Migration intermittently fails due to a service logon-related problem. The environment was previously working n...
Hi, I’d start with the cluster validation report and the event logs on both the source and destination node at the exact migration time. Live Migration problems usually come down to network selection, authentication, constrained delegation, CPU compatibility, VM configuration version, or storage/CSV access. Also confirm both hosts are at the same patch level and have matching processor compatibility settings if the CPUs are not identical. If this is a new Windows Server 2025 cluster, I’d test with a small clean VM first. If that works, the issue is probably VM-specific; if it fails too, focus on cluster networking and authentication.
