Hi, I am trying to release domU pages from page_list and xenpage_list after domU shutdown while retaining the rest of the domain information. To achieve this in __domain_finalise_shutdown i call domain_relinquish_resources. This is failing to release pages from page_list for type PGT_l2_page_tables and crashing dom0. To be specific, while testing on mini-os i saw that when domain_relinquish_resources calls relinquish_memory for PGT_l2_page_tables, this eventually calls free_l2_table which fails at map_domain_page() by returning an invalid virtual address, due to which dom0 crashes immediately. When the same sequence of functions works perfectly fine during domU destruction, why not during shutdown. Am I missing anything important? Am using xen-3.3-unstable.
