Hello, I haven't been able to open a crashdump generated by 'dump-guest-memory -z' option. When I run crash -d10 vmlinux dump.img last thing I get is: kaslr_helper: failed to determine which kernel was running at crash, kaslr_helper: asssuming the kdump 1st kernel. calc_kaslr_offset: kaslr_offset=ffffffff9ba00810 calc_kaslr_offset: phys_base=19a5ff7f0 crash: pv_ops exists: ARCH_PVOPS <readmem: 137e001e0, PHYSADDR, "linux_banner verify", 13, (ROE|Q), 7ffffe50ff50> <read_diskdump: addr: 137e001e0 paddr: 137e001e0 cnt: 13> read_diskdump: paddr/pfn: 137e001e0/137e00 -> cache physical page: 137e00000 gdb vmlinux GNU gdb (GDB) 7.6 Copyright (C) 2013 Free Software Foundation, Inc.
