similar to: Guest debugging fails for 32bit, works for 64bit

Hi Mukesh, I was auditing uses of set_xen_guest_handle for correctness when I noticed that gdbsx (specifically tools/debugger/gdbsx/xg/xg_main.c) defines its own _domctl_hcall and associated helpers instead of using libxc. Is there any particular reason for that? Ian. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com

I run a centos6.2 guest VM in xen4.1.2, the id of centos-domU is 22. The info of dom0 is: 2.6.32-131.21.1.el6.xendom0.x86_64 #1 SMP Tue Dec 13 18:09:29 EST 2011 x86_64 x86_64 x86_64 GNU/Linux Centos-domU: 2.6.32-220.7.1.el6.x86_64 #1 SMP Wed Mar 7 00:52:02 GMT 2012 x86_64 x86_64 x86_64 GNU/Linux At dom0, I went like this: [malei@xentest-4-1 Tue Apr 30 ~]$ sudo gdbsx -a 22 64 9999 Listening on

Hi, gdbserver-xen coredump after i step through a few lines of code. build dom0 with debug_domu. Enable debuginfo and frame pointer for dom U and attach the domu with gdbserver . In gdb put breakpoint at say sys_open and after going through few lines of code gdbserver-xen coredumps. The resulting core file has the below stack $gdb /usr/local/bin/gdbserver-xen ./core GNU gdb 6.3-debian

Hi, I followed the instructions in tools/debugger/gdb/README to enable the xen debugging feature. But after that my system (a kernel module) works 10 times slower. Maybe the debugger slows down the running. What''s the right way to reverse and disable the debugger? I tried to disable the "Kernel hacking -> Compile the kernel with debug info [*]" option. But it does not help.

Hi all, I thought this should be very simple, but I'm not sure where the problem is. I have a .txt data file that contains X and Y coordinates of trees and their family names: "X" "Y" "Mark" 0 28 "Sapotaceae" 1 30 "Meliaceae" 1 40 "Meliaceae" 1 60 "Mimosaceae" 1 76 "Olacaceae" 1.5 73 "Myristicaceae" 2

hi,all has anyone set the eflags.TF of vm? I want to introdeuce a VM into single-step by setting the eflags.TF of vm, then I disassemble the bytes at RIP to figure out what''s going on . I have set the trap flag ,but I didn''t achieve what I want. First, I only get hlt,mov, rdtsc, clts, in, out . Second, the VM always crash. does anyone have experience and give

Hello, I''m trying to get PDB working in accordance with the instructions at http://www.cl.cam.ac.uk/~sos22/replay.bk/docs/misc/XenDebugger-HOWTO and a message from this list: http://lists.xensource.com/archives/html/xen-devel/2004-08/msg00017.html When I try to build pdb I first get errors because the Makefile is configured to treat warnings as errors, and there are some warnings.

Hi Keir, Ian, Today if we stop the guest for debugging using the gdbserver and then continue with the guest execution the PIT finds that the time has gone ahead and it missed to inject so many timer ticks, and it tries to inject all of those one by one. So after the gdb continue command the guest just handles the timer interrupts for a long time before it can do anything else. This patch

hi, I am wondering if anybody is doing Xen or Dom0 debugging with gdb here. If yes, could you show me the procedure of doing that? Thanks, Neo -- I would remember that if researchers were not ambitious probably today we haven''t the technology we are using! _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com

Hi, kdb: to debug xen hypervisor, could also debug guests gdbsx: to debug PV/HVM linux guests The tree is : http://xenbits.xensource.com/ext/debuggers.hg See README-dbg.

This is not useful. You need to do something like: exec /usr/libexec/qemu-kvm -s

Folks -- One more time with the PAE request, this time I''ve brought up the Linux kernel w/ a very recent version of Xen. (Just yesterday I pulled and updated my hg tree.)

Hi all, this is the tenth version of the patch series to introduce upstream qemu and seabios in the xen-unstable build system. Changes to v9: - rename QEMU_UPSTREAM_TAG to QEMU_UPSTREAM_REVISION: we are going to use it with a branch name by default; - set QEMU_UPSTREAM_REVISION to "master" by default; - set SEABIOS_UPSTREAM_URL to git://xenbits.xen.org/seabios.git by default; - add

Heya, With latest Fedora Rawhide Kernel, I see a nested KVM guest hanging at boot (not unusual). Rich once suggested this[1] to try to attach gdb to the nested L2 guest to find out where_ it's stuck, tonight I set out to try it out (with KVM & TCG). Below is all what I tried. In guest hypervisor (L1): $ git clone git://github.com/libguestfs/libguestfs.git $ git log | head -1

Hello LLVMdev!! Yesterday I posted a patch request to the llvm-commits list requesting that someone could apply a patch to Triple.h and Triple.cpp for me. I didn't get any response so I wondered whether I should have posted to this list instead. My story is as follows: we are trying to get lldb/llvm support for CSRs range of Kalimba DSPs. Eventually we are planning to hire someone to
