doubt on releasing domain pages
...se_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.
Thanks in adva...
