   Recently I'm reading the code that will be used when a hvm domain is destroyed,including some importent methods such as domain_kill(),domain_relinguish_resource(),domain_destroy() and so on.
    Theoretically,there must be some methods that calls free_domheap_pages() and relinquish the domain's memory,however, I can't find the corresponding codes that do this job.relinquish_memory()  has something to do with this but not enouth,after this the memory is still held by the dead domain.
    I have read the source tree over and over,finding no clue.That's so frustrating.Can you give me some sugguestion?Thank you very much!
