similar to: How to disable xen debugger?

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

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.

These patches address issues in the kernel part of xenoprof: * Ill-advised use of on_each_cpu() can lead to sleep with interrupts disabled. * Race conditions in active_domains code. * Cleanup of active_domains code. Comments welcome. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

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

I''ve followed the instructions in tools/debugger/gdb/README for building and using gdbserver-xen. While playing around with debugging a running guest or dissecting a core file, I''ve discovered that using it with a 32-bit PV domU fails but it works fine on the same guest if it''s booted with a 64-bit kernel. Is this a known limitation, or am I doing something incorrectly?

New /sys/hypervisor/uuid, containing this domain''s UUID. Stripping off /vm/ from the value of vm to get the UUID isn''t exactly nice. The alternative is to add a XENVER_get_uuid code to HYPERVISOR_xen_version(), but I''m not sure that''s worth it.

This is a pair of Xen para-virtual frontend device drivers: drivers/video/xen-fbfront.c provides a framebuffer, and drivers/input/xen-kbdfront provides keyboard and mouse. The backends run in dom0 user space. I started with the Xen version at http://xenbits.xensource.com/linux-2.6.18-xen.hg?rev/ca05cf1a9bdc Differences to that Xen version, for those who care: * Rewritten on top of fb deferred

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

This is an update to the Linux part of the Xen PVFB.

I understand libguestfs comes with integration tests. You might be interested in something I'm developing for QEMU 5.0 to permit "testing the future". I'd like to ensure it is actually useful before I continue. Let me know what you think. = Motivation = When layers above QEMU somehow miss feature deprecation, things continue to work until the deprecated interface goes away,
