Reviewed-by: Juan Quintela <[email protected]> I don't have a better suggestion. Really we could allow migration to identical machines, but I assume that there is not a way to read the tsc frequency? (Althought reading the model name/numbers could be enough?) I.e. Add a subsection that includes the cpu model name, or whatever we can have to identify the host cpu? Later, Juan.
