Hi All, I have several questions about log dirty mode during live migration. For my understanding, each time after XEN_DOMCTL_SHADOW_OP_CLEAN or XEN_DOMCTL_SHADOW_OP_PEEK operation, all the pages are set as read only. The following memory accesses to the memory pages will cause page fault (permission conflict) then using page_mark_dirty function to set the dirty bitmap. However, after I read

...Olaf Hering <olaf@aepfle.de> date: Thu Oct 06 12:52:18 2011 +0100 p2m: use correct p2m_type_t in clear_mmio_p2m_entry clear_mmio_p2m_entry() should mark the gfn as invalid. Use proper name instead of numerical value. The currently used value of zero means p2m_ram_rw.

Hi, Olaf we have tested the xenpaging feature and found some problems. (1) the test case like this : when we start a VM with POD enable, the xenpaging is started at the same time. this case will cause many problems ,finally, we fixed the BUG, the patch is attached below. (2) there is a very serious problem. we have observed many VM crash examples, the error code is not always the same.

Populate-on-demand: Check pages being returned by the balloon driver This patch series is the second result of my work last summer on decreasing fragmentation of superpages in a guests'' p2m when using populate-on-demand. This patch series is against 4.1; I''m posting it to get feedback on the viability of getting a ported version of this patch into 4.2. As with the previous

This patch series includes a series of bugs related to p2m, ept, and PoD code which were found as part of our XenServer product testing. Each of these fixes actual bugs, and the 3.4-based version of the patch has been tested thoroughly. (There may be bugs in porting the patches, but most of them are simple enough as to make it unlikely.) Each patch is conceptually independent, so they can each

This patch series tidies up a few bits ofthe nested p2m code. The main thing it does is reorganize the locking so that most of the changes to nested p2m tables happen only under the p2m lock, and the nestedp2m lock is only needed to reassign p2m tables to new cr3 values. Changes since v1: - a few minor fixes - more sensible flushing policy in p2m_get_nestedp2m() - smoke-tested this time!

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
