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? -Thomas _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
