Thread-topic: [Xen-devel] 'qemu-dm' process just died
User-agent: Microsoft-Entourage/11.3.3.061214
You can't get a core dump from a defunct process, but if you want a core
dump in future then you can invoke qemu-dm from a script which first does a
'ulimit -c <max_core_size_kilobytes>'. Easily done by using 'device_model='
config option in domain config file, or rename qemu-dm binary and install a
script of the same name in its place.
Tools/ioemu/target-i386-dm/qemu-dm.debug gives an example of how to invoke
the real qemu-dm from within a script, keeping its arguments properly intact
and unmangled.
