You may get this error when you want to migrate a virtual machine with Live Migrate.
Virtual machine X could not be live migrated to virtual machine host Y using this cluster configuration.
(Unspecified error (0×80004005))
Check the cluster configuration and then try the operation again.
Check available memory (ram) on host Y. Maybe you have enough ram to pass SCVMM pre-checks but you don’t have enough to use Cluster service. Save state another virtual machine on host Y and retry migrate.
