Re: [Xen-devel] How to analyze "xm dump-core"

[tom anderson <xentoma@xxxxxxxxxxx>]

I have tried using gdbserver with a core file (xen-4.0-testing) after patching tools/libxc/xc_ptrace_core.c.

A bt gives an error message "Cannot access memory".

  (gdb) bt

  #0  native_safe_halt () at /import/tonic/bedge/osa/kernel/ubuntu/linux-2.6.32/arch/x86/include/asm/irqflags.h:50

  Cannot access memory at address 0xffffffff818cfed0

I noticed that gdbserver has been removed from xen-unstable.

Has anyone successfully analyzed the core file resulting from xm dump-core?
