This sounds a bit like an issue discussed in the Redhat libvirt troubleshooting FAQ

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Virtualization_Deployment_and_Administration_Guide/sect-Troubleshooting-Common_libvirt_errors_and_troubleshooting.html#sect-Migration_fails_with_Error_unable_to_resolve_address

Right. If it is a DNS issue, error handling in the libvirt libxl migration code 
needs improving.
