Troubleshooting Live Migration issues on Hyper-V

1. Check whether enough resources (CPU, RAM) are available at the destination host
2. Make sure all nodes in the cluster follow same naming standard for vSwitches
3. Check NUMA spanning is enabled or not. If NUMA spanning is disabled, VM must fit entirely within a single physical NUMA node or the VM will not start or be restored or migrated
4. Constrained delegation should be configured for all servers in the cluster if you are using Kerberos authentication protocol for live migration
5. Check live migration setting is enabled on Hyper-V settings
6. Verify Hyper-V-High-Availability logs in event viewer
7. Finally check cluster debug log (Get-Clusterlog -timespan) in C:\Windows\Cluster\Reports\Cluster.log
