similar to: [PATCH] x86: also print CRn register values upon double fault

This series consists of improvements to Xen''s ability to print traces of its own stack, and specifically for the stack overflow case to be able to use frame pointers in a debug build. I have dev tested the series in debug and non-debug cases, with and without memory guards, and I believe that all the stack traces look correct (given the available information Xen has), and that the

In this patch, we change read_segment_register to take vcpu and regs parameters for PVH (in upcoming patches). No functionality change. also, make emulate_privileged_op() public for later.

This patch series is a reworking of a series developed by Mukesh Rathor at Oracle. The entirety of the design and development was done by him; I have only reworked, reorganized, and simplified things in a way that I think makes more sense. The vast majority of the credit for this effort therefore goes to him. This version is labelled v13 because it is based on his most recent series, v11.

Thanks Richard for a fast reply. Yes, indeed, im working on a nested environment. I try to run v2v inside a VM (L1) and to create an L2 by the conversion process. And on Intel. As I wrote, it fails once in few times, mainly when there is a memory pressure on L0. Kashyap, can you please share your experience? Why should it crash during nested conversion. I'm not too familiar with libguestfs

Kashyap, just to be sure - it happens to you during the v2v conversion? on L2? While L1 and L0 works fine afterwords, right?

Hi everybody, Wanted to hear your opinion and to receive a smart advice. I'm trying to use virt-v2v in order to convert ova image (exported from vcenter) to run on libvirt/kvm - all this inside a VM of fedora. The converted image is also a fedora. During the conversion process, in some point of libguestfs activity, I get double fault panic from L2 (printed as part of libguest output) and the

The guestfsd daemon is simply running the regular 'mount' command. The mount command causes the kernel to panic. There should be no circumstances where running an ordinary command like that, albeit as

Hey everybody, Richard, you were right. I managed to reproduce the same crash without dealing with v2v (and libguestfs). Actually - it's reproducible really ease - I write a big file to /tmp on L0 (till it 100% full) and then run a L2 VM. Almost every time it crushes with double fault. Debugging, debugging and more debugging. Marcelo/Paolo, if you have any clue, I would like to hear from you.

Use NOKPROBE_SYMBOL macro to protect functions from kprobes instead of __kprobes annotation in trap.c. This also applies __always_inline annotation for some cases, because NOKPROBE_SYMBOL() will inhibit inlining by referring the symbol address.

This set of patches converts the way frames gets created from using PUSHes/POPs to using MOVes, thus allowing (in certain cases) to avoid saving/restoring part of the register set. While the place where the (small) win from this comes from varies between CPUs, the net effect is a 1 to 2% reduction on a combined interruption entry and exit when the full state save can be avoided. 1: use MOV

That change converted the (wrong) assumption of contiguous nodes'' memory to a similarly wrong one of assuming discontiguous memory (i.e. each node having separate E820 table entries). The code ought to be able to deal with both, though, and I hope this change makes it so. Signed-off-by: Jan Beulich <jbeulich@novell.com> --- 2009-08-24.orig/xen/arch/x86/srat.c 2009-08-28

Sometimes the UEFI memory map changes between GetMemoryMap() and ExitBootServices(), making the MapKey value incorrect. Per the UEFI spec, the memory map should then be fetched again and exiting retried.

Attached and below are a patch that unifies the shutdown code paths in Xen, including those from EARLY_FAIL. This will facilitate the use of Intel(R) TXT for measured launch by ensuring that all shutdowns will call the necessary hook to tear down the measured environment. It also centralizes any future shutdown-related changes. The patch also postpones clearing the online status APs in
