Windows Server / Hyper-V & Failover Clustering
Inspect live-migration prerequisites before retrying a failed move
A live migration can fail because of authentication, network policy, destination capacity or storage access. Record the configured host settings.
Environment and inputs: Windows Server 2022 / 2025 baseline · Windows PowerShell with the specified role or RSAT modules; native utilities are identified in the text. Use delegated administration and elevation only where required.
Start with this check
Confirm the host, shell and access role. Replace sample names, paths, domains and interfaces with approved targets. These are diagnostic commands; assess policy and workload impact before making changes.
Get-VMHost | Select-Object VirtualMachineMigrationEnabled, VirtualMachineMigrationAuthenticationType, VirtualMachineMigrationPerformanceOptionRead the result
The values describe this host's migration configuration. Destination settings, delegation and actual event errors are also required.
Resolve and verify
Compare both hosts and the migration error, then repair the specific credential, transport or capacity dependency. Validate a controlled move in the approved window.
Before changing production
Do not change authentication globally or repeatedly move a busy production VM while the failure cause is unknown.
