Storage migration from pooled to local storage fails under XS Dundee beta.1

Xenmotion fails with the wizard to move to a different XenServer when going from pooled to local storage. A VDI move on the same server also fails to move a VDI from pooled storage to local storage on the same XenServer, A huge amount of free space on both the current and target SRs is available in all cases. The error message is always "the VDI was not mapped to a destination SR in VM.migrate_send operation". The detailed xensource.log captured during one of the transfer attempts is attached.
