This patch series restores the use of superpages when restoring or migrating a VM, while retaining efficient batching of 4k pages when superpages are not appropriate or available.

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

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.

Hi, I have a question about memory page tables in Xen. As far as I understood, every modification to page table will go through Xen(hypervisor). Is it so that all page tables are actually allocated in Xen(hypervisor) instead of guest OS(domain)? Also, is it the case that Xen(hypervisor) needs to maintain a page table for each process running in every domain? Thanks Haifeng

I would like to know approximately the overall execution flow when the guest O/S page fault - how is the page fault transfer to a page fault in the host O/S? Thanks. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi, --- background ---------------------------------------------------- * what the makedumpfile is: To shorten the size of the dumpfile and the time of creating the dumpfile, makedumpfile copies only the necessary pages for analysis to the dumpfile from /proc/vmcore. You can specify the kind of unnecessary pages with dump_level. If you want to shorten the size further, enable the

Hi, all Page offline can be used by many purpose, like memory offline, memory power management, proactive action when multiple CE error happen to one page etc. In virtualization environment without guest offline support, we think offline a page usually means replace the old page with a new one transparently to guest. Currently we are trying to add page offline support in Xen environment .

I''m not seeing the problem that Fan Zhao is reporting, instead I get this one. Not sure if ti''s the same one or a different problem... This happens with my simple-guest [i.e. not using hvmloader, as I described before]. This worked fine yesterday. (XEN) event_channel.c:178:d0 EVTCHNOP failure: domain 0, error -22, line 178 (XEN) bad shared page: 0 (XEN) domain_crash_sync called

The patch deals with the situation which guest OS uses unused page table pages as data pages and write data to them. The pages will still be grabbed by Xen as page table pages, and lots of unnecessary page faults occur. The patch will check if the data guest writes to the page table contains valid mfn or not, if not, we believe it is a data page now and then unshadow the page. The patch

Hi all, I had posted about MCA support for Intel64 before. It had only a function to log the MCA error data received from hypervisor. http://lists.xensource.com/archives/html/xen-devel/2008-09/msg00876.html I attach patches that support not only error logging but also Page Offlining function. The page where an MCA occurs will offline and not reuse. A new flag ''PGC_reserved''

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

Hello, Recently many advanced memory mechanisms are introduced into Xen. One problem we found is the conflict between p2m query and setting. For example, backend drivers always map domU’s page to its own space, during the mapping procedure, situations as follow may happen, when mfn is obtained by gfn_to_mfn(), this mfn is likely to be paged out. first case: grant mapping

Hi, Keir, These patches are rebased version of Yunhong''s original patches, which were sent out before XEN 3.2 was released. These patches enable MSI support and limited MSI-X support in XEN. Here is the original description of the patches from Yunhong''s mail. The basic idea including: 1) Keep vector global resource owned by xen, while split pirq into per-domain

This issue was brought up about a year and a half ago. So I''ll bring it up again and see if anything happens. I''ve got an infiniband network and am attempting to pass the infiniband card through the host and give it to the guest. I''m working with standard CentOS 5.2 on both guest and host with their provided xen (3.0.3 ish). I''ve also attempted to install the

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

I was trying to patch Xen 3.2 from the mercurial repository with the MSI patches by Yunhong Jiang given at the bottom of this page : http://lists.xensource.com/archives/html/xen-devel/2007-11/msg00157.html The tree seems to have significantly changed, especially the hvm_irq_dpci_mapping structure in irq.h header file. Are there any updated patches, or can I get a version of Xen from somewhere
