Server 2012 Hyper-V live migration via SMB problem

[guest]

I have 2 Hyper-V servers both joined to a domain and I can do live migration between them using local storage - works great. I wanted to try with an SMB share. So I created a share on one of the 2 HyperV servers (servers are 10.10.10.5 and 10.10.10.15) The share is located at \\10.10.10.15\smbshare - so on each server i mapped the Z drive to this. So yes, one hyper-V server has an SMB share and a drive mapped to intself. The VM is installed on 10.10.10.5 and was installed using drive as the install location. VM starts and runs fine, but when i go to migrate just the VM - I get an error:

'': account does not have permission required to open attachment '\\10.10.10.15\smbshare\Win8Beta\Virtual Hard Disks\Win8Beta.vhdx'. Error: 'General access denied error' (0x80070005). (Virtual machine ID )

Both machine accounts have full permissions on the share; Delegation for all protocols via Kerberos is set. Could this be due to my "loopback" share? I don't remember this in past versions of windows, but i think i confirmed it as i can't even create a new VM using the VHDX when i use this loopback share.

Anyone know of a workaround? I Just have 2 physical servers for testing - I would never do this in production.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this

jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
