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 imme...

I know you Xen developers are beginning to hate me ;) but... While trying to compile 2.4.24 under DOM0, quickly after issuing ''make dep'' I got: Kernel panic: Failed mmu update: c015bf80, 4 I suspect this address probably isn''t to helpful but this is all I have. I am currently booted in 2.4.21-SuSE and compiling the 2.4.24 regarding another thread here. Regarding

Hi, V6: The only change from V5 is in patch #6: - changed comment to reflect autoxlate - removed a redundant ASSERT - reworked logic a bit so that get_page_from_gfn() is called with NULL for p2m type as before. arm has ASSERT wanting it to be NULL. Tim: patch 4 needs your approval. Daniel: patch 5 needs your approval. These patches implement PVH dom0. Patches 1 and 2
