Daniel, Kashyap,

One question that came up on IRC was, how/where to configure say a
directory where core dumps from qemu would end up. Sean was seeing a
scenario where he noticed a core dump from qemu in dmesg/syslog and
was wondering how to specify a directory to capture a core dump
if/when it occurs.

thanks,
dims
