Cluster resource ‘Virtual Machine XXX’ of type ‘Virtual Machine’ in clustered role ‘XXX’ failed in windows 2012 hyperv cluster

Cluster resource ‘Virtual Machine XXX’ of type ‘Virtual Machine’ in clustered role ‘XXX’ failed. The error code was ‘0x80004005’ (‘Unspecified error’).

Based on the failure policies for the resource and role, the cluster service may try to bring the resource online on this node or move the group to another node of the cluster and then restart it. Check the resource and group state using Failover Cluster Manager or the Get-ClusterResource Windows PowerShell cmdlet.


Live migration of ‘Virtual Machine VM’ failed.

Virtual machine migration operation for ‘VM’ failed at migration destination ‘HYPERVHOST’. (Virtual machine ID AFDD9E40-58EF-4364-AF83-0EA9F4B54C0E)

The virtual machine ‘VM’ is using processor-specific features not supported on physical computer ‘HYPERVHOST’. To allow for migration of this virtual machine to physical computers with different processors, modify the virtual machine settings to limit the processor features used by the virtual machine. (Virtual machine ID AFDD9E40-58EF-4364-AF83-0EA9F4B54C0E)


This may happen if you are running hyper-v cluster with different hardware especially you are mixing up a latest server and a old box.

Just shutdown the VM and open settings in cluster manager, make sure Migrate to a … is selected under Processor>Compatibility
