Hello,
We have 4 Hyper-V clusters all managed by SCVMM. We recently migrated SCVMM into the same domain as the Hyper-V clusters and also upgrade to a newer version of SCVMM. Now when trying to migrate a VM (that is turned off) from one cluster to another it fails.
Error (12700) VMM cannot complete the host operation on the 'CLUSTER1HOST1.mydomain.tld' server because of the error: Virtual machine migration operation for 'MYVMTOMIGRATE' failed at migration source 'CLUSTER1HOST1'. (Virtual machine ID <GUID>) The Virtual Machine Management Service failed to establish a connection for a Virtual Machine migration with host 'CLUSTER2HOST1.mydomain.tld': The credentials supplied to the package were not recognized (0x8009030D). Failed to authenticate the connection at the source host: no suitable credentials available. Unknown error (0x8000) Recommended Action Resolve the host issue and then try the operation again.
The live migration authentication method is CredSSP and everything I have found online related to this error says to switch to Kerberos authentication with delegation.
That is fine but Im trying to understand why CredSSP no longer works when it once did. We do have Hyper-V Replicas on these clusters using Kerberos authentication. Im not sure if those setting might conflict with each other or not. Its been a while since I last used the Live or Offline Network Migration and the Replica feature was enabled after we last used it.
Thanks.
