Subject: tools to dump guest memory and generate core file
Date: Sun, 16 Mar 2008 21:02:27 -0600 [thread overview]
Message-ID: <47DDDF43.9020008@cisco.com> (raw)
Does anyone know of tools that can dump memory for a qemu guest with addresses
as seen by the guest and generate a core file? For instance, say you know the
guest is running a 32-bit linux kernel with a 1G/3G split. Then you would want
to dump 1G of memory starting 0xc0000000 and create an ELF core file. The core
file could then be analyzed using tools like crash (or gdb for the truly
adventurous).
I know VMware can take a snapshot and generate such a core file. Does a similar
tool exist for qemu? I see that the qemu console supports a raw memory dump, so
it should be possible. (Note I am not talking about a core file of the qemu
process, but rather a core file based on guest memory addressing.)
