Migration/Live Migration fails with shared storage (SMB), but not all the time

Question

I have 2 Hyper-V Hosts using shared storage via SMB. I'm having intermittent issues with migrations failing. It'll either go through the motions of doing the whole move and fail and/or when I try to start it again I get the following:
I've done a lot of reading on this and have done various things that have been recommended. For each Hyper-V host I've setup delagation via Kerberos. ie. HV_Host1 has CIFS - HV_Host2; CIFS - SMB Server; MS Virtual System Migration Service - HV_Host2 and
vice versa.
On the actual SMB share on the Shared Storage server I added permissions to the folder for HV_Host1, HV_Host2, Storage Server, Domain Admins and my user account for full access.
In Group Policy, I've blocked Inheritance for the OU containing the Hyper-V hosts, though I have added some of the Group Policy's manually that I needed.
Last thing, I also added Domain Admins to the Local GP on each Host for "Log on as a Service" and "Impersonate a client after authentication" as shown in this thread: http://social.technet.microsoft.com/forums/windowsserver/en-US/7e6b9b1b-e5b1-4e9e-a1f3-2ce72ea1e543/unable-to-migrate-create-vm-hyperv-cluster-2012-logon-failure-have-to-restart-the-hyperv
I get these failed migrations regardless if I start them on the actual Host or via the admin console from Win8.
At this point I'm not sure what else to check or the next step to take for this.
