[V6 PATCH 0/7]: PVH dom0....
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

[PATCH 0 of 4] Use superpages on restore/migrate
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.

Some problems about xenpaging
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.

[PATCH 0 of 3] RFC Paging support for AMD NPT V2
There has been some progress, but still no joy. Definitely not intended for inclusion at this point. Tim, Wei, I added a Xen command line toggle to disable IOMMU and P2M table sharing. Tim, I verified that changes to p2m-pt.c don''t break shadow mode (64bit hypervisor and Win 7 guest). Hongkaixing, I incorporated your suggestion in patch 2, so I should add your Signed-off-by eventually.

odd gfn number checking in p2m.c
Hello, how can a gfn become 0x555555 as checked in p2m.c:guest_physmap_add_entry() and p2m_alloc_table()? Looking further in p2m.c, audit_p2m() checks only for a 32bit value. So where is that magic number set, and why is it not a define to simplify grepping for users of that value?

[PATCH 0 of 3] Miscellaneous populate-on-demand bugs
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

[PATCH 0 of 2] v2: memshare/xenpaging/xen-access fixes for xen-unstable
The following two patches allow the parallel use of memsharing, xenpaging and xen-access by using an independent ring buffer for each feature. Please review. v2: - update mem_event_check_ring arguments, check domain rather than domain_id - check ring_full first because its value was just evaluated - check if ring buffer is initialized before calling mem_access_domctl/mem_paging_domctl

Xen 3.0.4 - Ballooning
Hi, Maybe it''s a dumb question, but I''m actually trying to understand how the memory allocation works within Xen. I try to give 128MB to a domU and see if it increases for example when I "nano" a 500mb file, but the process just get killed when it reachs the 128MB memory limit. How do I configure the guests so they can ask for more memory until a limit is reached

[PATCH 0 of 4 RFC] Populate-on-demand: Check pages being returned by the balloon driver
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

[PATCH 0 of 2] Fix correctness race in xc_mem_paging_prep
ging_prep ensures that an mfn is backing the paged-out gfn, and transitions to the next state in the paging state machine for this page. Foreign mappings of the gfn will now succeed. This is the key idea, as it allows the pager to now map the gfn and fill in its contents. Unfortunately, it also allows any other foreign mapper to map the gfn and read its contents. This is particularly dangerous

performance counters
In order to be meaningful and usable together with other measuring methods, their use in my opinion should impose as little overhead as possible. With that, I wonder why per-cpu counters use atomic operations.

[PATCH] Fix arguments passed to SHADOW_PRINTK
Hi. When I compiled xen-3.3-testing with DEBUG_TRACE_DUMP in xen/include/xen/lib.h turned on, I got some errors at SHADOW_PRINTK. The following patch will fix the arguments passed to SHADOW_PRINTK in xen/arch/x86/mm/shadow/common.c and xen/arch/x86/mm/shadow/multi.c. Although I haven''t tested, it is the same for xen-unstable.hg Thanks, Yoshi Signed-off-by: Yoshi Tamura

Xen HVMs run VERY slowly on SAN box
We are running a 2-node cluster with Debian Squeeze (2.6.32-5-xen-amd64) and Xen 4.0.1 on the dom0 and Ubuntu lucid domUs. We are now using fully virtualized (HVM) vms. In our configuration the dom0 administers to domUs created and run on a SAN box accessed via private network (192.168...). A sample configuration file is pasted below. We have had little or no IO problem with HVMs created and

[PATCH] ept: Fix bug in changeset 22526:7a5ee3800417
This fixes a bug in changeset 22526:7a5ee3800417, where the wrong value is read when deciding whether to flush the VTd tables. The effect is minor: in situations where the p2m entry is changed but the mfn is the same, the VTd tables will be unnecessarily flushed. old_entry is left untouched in the second case, since having a present old_entry will cause the an unnecessary check to be taken at

better define: matrix comparison and cbind issue
Hello, Sorry to all for the lack of communication, and thanks to those with the suggestions. So I have two matrixes which are different sizes, same column number but different row number. What I would like to do is to compare A to B. In the 6 and 9th column there are ref numbers (molecular masses to be exact). I would like to check A and B by these columns. If I find that the number in A[9,x]
