Thanks. Great job. Basically, it says that it is impossible to use live 
migration in production environment with tunneled transport for libvirt.

To test live migration we simulated a case of 0-day patching of 100 compute nodes (including reboot) with workloads that are close to the real world workloads. All the results were published [1] along with environment configuration and how we built test framework. Hope you find this useful.
