Can‘t live migrate virtual Machines in failover cluster.

Question

Hi,
We can't live migrate our virtual machine in our failover cluster. And We find some virtual machine can live migrate successfully but some failed.
In our failover cluster, We have 8 nodes. And these nodes have different processor model(process version.jpg). But we have checked the box on the properties of virtual machine(allow_migrate.jpg). And we also allow migrate in hyper-v setting(migrate_settings.jpg)
Because I can't upload the cluster validation report, So I will upload some pictures that have warning items.
We want to know why we can't live migrate some virtual machines and how to resolve it?!

Answer 1

Hi,

1. According to your description, we have several VMs that failed to live migration to other nodes in the Cluster, since different VMs may have different issues, it's recommended to force on one VM moving from one node to another node issue. If the resolution also works for other VMs, the issue may be the same. If not, we need to open a new case to resolve the other VM live migration issue.
2. If you agree, please try to select one VM, try to live migrate it from the current node to the destination node, after reproducing the issue, please check the Hyper V VMMS log in Event Viewer>Applications and Services Logs>Microsoft>Windows>Hyper V VMMS both on source node and destination node, then provide the error message for us.
3. If the live migration fails, please check if quick migration works? If quick migration works, please check if the VM could start on the destination node, if not, please provide the error message when starting the VM.

Thanks for your time!
Best Regards,
Anne
