Re: [Crash-utility] crash-utility for inspecting FreeBSD VM dump

Hi everyone, I am curious for inspecting FreeBSD VM dump by crash-utility. I built crash from source, and changed the configure option of gdb to target FreeBSD. And used virsh dump --memory-only to generate freebsd.dump. But I got an obstacle when use this crash utility to load FreeBSD dump: # ./crash/crash ./kernel.debug ./freebsd.dump crash 7.1.4 Copyright (C) 2002-2015 Red Hat, Inc.
