[RFC][PATCH] Kemari v1.0 released
Hi,
I would like to announce the first release of Kemari, an open-source
virtual machine synchronization mechanism for fault tolerance.
It offers a feasible approach to fault tolerance that does not
require the use of specific hardware or modification of applications/OS.
Kemari aims to keep VMs transparently running in times of hardware
failures. It transfers the state of the primary VM to the

Consult some concepts about shadow paging mechanism
Dear All:
I am pretty new to xen-devel, please correct me in the following.
Assume we have the following terms
GPT: guest page table
SPT: shadow page table
(Question a) When guest OS is running, is it always using SPT for
address translation? If it is the case, how does guest OS refer and
modify its own GPT content? It seems that there is a page table entry
in SPT for the GPT page.

[PATCH] Minor fix to the fast emulation patch.
Hello,
The fast emulation path patch introduced a bug when we have an event
injection during a write to a pagetable: after removing shadows we
still jump to the done label, releasing the lock even if we aren''t
grabbing it.
Inline patch fixes this.

VT-d and the GPU
Like others on this list I am trying to employ the VTD-NEO patches in
Xen 3.2 unstable to assign the internal graphics device to Dom1/Vista.
I have removed the Cirrus Logic emulated device from qemu and replaced
the Cirrus Logic vgabios with the the actual vgabios from my GPU.
However I am hitting an xen assert and was hoping someone might be able
to point me in the right direction. Below

question about memory auto-translate and paravirtual and no pseudophysical overlay
hi
I try to understand the code of xen memory
there are gmfn, gpfn and pfn in the xen
and in the /xen/include/xen/mm.h there are some explanation about them
as follows:
* 1. gpfn/gpaddr: A guest-specific pseudo-physical frame number or address.
* 2. gmfn/gmaddr: A machine address from the p.o.v. of a particular guest.
* 3. mfn/maddr: A real machine frame number or address.

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

Mixed conditional logit model

[PATCH 0/5] dump-core take 2:
The following dump-core patches changes its format into ELF,
adds PFN-GMFN table, HVM support, and adds experimental IA64 support.
- ELF format
Program header and note section are adopted.
- HVM domain support
To know the memory area to dump, XENMEM_set_memory_map is added.
XENMEM_memory_map hypercall is for current domain, so new one is created.

[PATCH] xen/arm: Allow balooning working with 1:1 memory mapping
With the lake of iommu, dom0 must have a 1:1 memory mapping for all
these guest physical address. When the ballon decides to give back a
page to the kernel, this page must have the same address as previously.
Otherwise, we will loose the 1:1 mapping and will break DMA-capable
device.

Mapping hvm guest pages in Dom0
hello,
I would like to map (Read/Write) pages owned by a HVM guest from my Dom0
Linux kernel module. I have access to the "machine frame numbers" of these
pages.
1. What is the right interface to do this? kmap needs ''struct page'' ptrs
which I doubt exist for pages owned by a HVM guest. Is there a hypercall to
do this then?
2. Do I need to modify the HVM behavior in

X86_64 "assert" when booting 64-bit image.
I can boot a 64-bit HVM image on my SVM-system, and it goes quite a long
way before it crashes (due to not finding the hard-disk image and thus
no root FS - which I think may well be the configuration file).
But if I set debug=y in the Rules.mk, I don''t get very far at all - it
crashes well before it gets to any user-mode (Ring3) - in fact, I think

[PATCH] Support cross-bitness guest when core-dumping
This patch allows core-dumping to work on a cross-bit host/guest configuration, whereas previously that was not supported. It supports both PV and FV guests. The core file format generated by the host, needs to match that of the guest, so an alignment issue is addressed, along with the p2m frame list handling being done according to the guest size.

[PATCH v7 1/2] xen: unify domain locking in domctl code
These two patches were originally part of the XSM series that I have
posted, and remain prerequisites for that series. However, they are
independent of the XSM changes and are a useful simplification
regardless of the use of XSM.
The Acked-bys on these patches were provided before rebasing them over
the copyback changes in 26268:1b72138bddda, which had minor conflicts
that I resolved.
