Because the memory size for x86 machine can greater than 4G, so we should create elf64 format core file for 32bit OS. I create a vmcore: the guest OS is 32-bit, and the vmcore is elf64 format. I can use crash to anaylyze it, but gdb can not do the same thing. I create a kdump-elf64 vmcore on 32-bit machine, and gdb still can not anaylyze it. Does gdb support elf64 format core file on x86 box? Thanks Wen Congyang > > Jan >
