Given the amount of code and the lack of traction at that time, I haven't respinned until now. However a recent bug found related to the ITS migration convinced me that this work may deserve to be respinned and enhanced. Tests exercise main ITS commands and also test migration. With the migration framework, we are able to trigger the migration from guest and that is very practical actually. What is particular with the ITS programming is that most of the commands are passed through queues and there is real error handling. Invalid commands are just ignored and that is not really tester friendly.
