Hey,

    I have a HVM with WindowsXP. Then use  "xm dump-core"  create a dump. How to  analyze it?

    I want to use windbg, but it can't analyze the dump's foramt.

    From google, maybe have a tool  can "convert ELF core dump to WinDbg recognized Windows kernel memory dump".

    how to find it?

    thanks

VirtualIron had a little tool for this. You can find VirtualIron dom0
sources at: http://virtualirondom0.com. Look in
./nex/dom0/tools/dumpconvert directory. You probably will have to modify
it a bit to work with the latest Xen.

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?
