Error 12700 Scvmm 2012
to vote I am in the process of Migrating all my Virtual Servers from a 2012 Cluster failed to authenticate the connection at the source host no suitable credentials available (CSV based) to a new 2012R2 Cluster (using SMB SOFS shares), all servers reside in the same domain, no constrained delegation is setup, all servers are in no credentials are available in the security package (0x8009030e) the same OU, I am using CREDSSP Authentication on My host settings, I have read online you don't need Kerberos when using SCVMM or delegation. Quick migration works fine with no issues. but live migration always fails :- Error (12700) VMM cannot complete the host operation on the SP-VHCC08.astonmartin.int server because of the error:
The Credentials Supplied To The Package Were Not Recognized Hyper-v

BrindSeptember 11, 20142 0 0 0 I have recently been working on a project that involves migrating VMs between hyper v there was an error during move operation clusters. This project came about due to a desire to virtual machine migration operation failed at migration destination upgrade the storage and host hardware within the infrastructure. We investigated the possibilities of using Failover
The Hardware On The Destination Computer Is Not Compatible
Cluster Manager to migrate the VMs/Roles between clusters, however in this instance that method did not fit, due to the method requiring that the old storage https://social.technet.microsoft.com/Forums/office/en-US/3707fe7c-deb1-4f1b-9f1b-ed68b6089bc5/live-migration-between-clusters-failes-using-scvmm-0x80072746?forum=winserverhyperv be mapped to the new hosts (not possible due to hardware restrictions), also perhaps more importantly this method would incur downtime! In addition to the environmentbeing amature Hyper-V estate, we were also very fortunate that the customer had previously chosen to centrally manage their environment using SCVMM 2012 R2. Within VMM, since SP1, https://blogs.technet.microsoft.com/virtual-mite/2014/09/11/virtual-machine-migration-operation-failed-at-source-an-existing-connection-was-forcibly-closed/ we have the ability to perform cluster-to-cluster Live Storage Migrations, also referred to as"Live (VSM)" during the wizard.(AMAZING, I know!). For more details see: http://technet.microsoft.com/en-us/library/jj628158.aspx So using the Live (VSM) feature in VMM we attempted to migrate a single VM, which worked perfectly. We then set about migrating further machines, however after 3 successful migrations, the 4th FAILED!. We attempted the same migration shortly after and it COMPLETED! whilst working through the list of VMs we saw a number of RANDOM failures, all producing the following error (Error (12700)): The same error may also appear when attempting a Storage Migration using the Hyper-V Manager console: Whilst investigating the error messages, I found that the Live Migration authentication method was set to CredSSP, instead of Kerberos (see for details: http://technet.microsoft.com/en-us/library/jj134199.aspx). After configuring all hosts with Constrained Delegation, we no longer received the above error when performing Live (VSM) migrations, in VMM,between clusters. Although the initial issue had be

The strange thing is that there is a destination folder in the new location, it's just does not copy content to that folder and aborts with the Access Denied error. But If you shutdown the VM first, so it' s just a migration over the Network, it works! The solution is to give the SOURCE Cluster Write Access on the DESTINATION Storage. When you do a VSM Migration, the destination Hyper-V host, creates the Directory on the S
