[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

[PATCH 0 of 5] v2: Nested-p2m cleanups and locking changes
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!

[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

How to create shadow page table of my own?
Hi, guys
Recently I have been doing some research & I''ve got in trouble.
I have altered the kernel of domU and put the code section and data section of selinux security server which locate ~/security/selinux/ss into two seperate sections in the final vmlinux image(see below)
objdump -h vmlinux

[PATCH] x86: allow Dom0 read-only access to IO-APICs
There are BIOSes that want to map the IO-APIC MMIO region from some
ACPI method(s), and there is at least one BIOS flavor that wants to
use this mapping to clear an RTE''s mask bit. While we can''t allow the
latter, we can permit reads and simply drop write attempts, leveraging
the already existing infrastructure introduced for dealing with AMD

Why is cpu-to-node mapping different between Xen 4.0.2-rc1-pre and Xen 4.1-unstable?
My system is a dual Xeon E5540 (Nehalem) HP Proliant DL380G6. When
switching between Xen 4.0.2-rc1-pre and Xen 4.1-unstable I noticed
that the NUMA info as shown by the Xen ''u'' debug-key is different.
More specifically, the CPU to node mapping is alternating for 4.0.2
and grouped sequentially for 4.1. This difference affects the
allocation (wrt node/socket) of pinned VCPUs to the

Memory sharing
Hi,
Currently i''m going through the source codes of tools/blktap2. I need to
find-out where blktap2 calls
1. mem_share_nominate()
2. mem_sharing_share_page() functions to do the memory sharing on HVM
guests.
Can someone please provide me some guidance on blktap2 driver.
Thanks,

(strange idea) unfriendly migration
Good day.
As we all know, xen requires assist from VM to migrate it. If VM will
acts wrong during migration, it will crash, or behave strangely until
reboot (nice sample - default -xen kernel in lenny).
We need to accept changes in domU during migration: other domain id,
new vbd/vif and so on.
This fine until we talks about friendly VM. But if VM is not very
friendly? For example, VM''s

[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

[PATCH] Replace bios_relocate hook with bios_load hook in hvmloader
Hi,
These set of patches are affected by replacing bios_relocate hook with
bios_load hook in hvmloader. The patches for code files config.h and
hvmloader.c also contains part of the contents of Enabling UEFI BIOS(OVMF)

can dom0 modify Shadow PT of HVM domU?
Hi all,
Can Xen hypervisor modify HVM domU's Shadow page table, under the dom0's context, like trapped from dom0's hypercall?
I think it have to call 2 functions at least: guest_walk_tables() and flush_tlb_all(). Can these 2 functions called in dom0's context?
In my test, if hypervisor tries to modify HVM's shadow page table, it will bring down the whole system. I am not
