[Qemu-devel] automatic exit on memory errors

[Frediano Ziglio]

Hi,
  I just realized that on any out of memory conditions Qemu exit with an error.

I found this thread on g_malloc

    http://comments.gmane.org/gmane.comp.emulators.qemu/128863

but nothing related to the exit conditions.

I know that out of memory conditions is quite hard to handle but if
somebody rely to a virtual machine and at least to a clean close I
think this won't happen. Personally I think that managing this
situation in a clean way where error is tried to be reported and
cleans are tried.

If some function try to allocate a large buffer the function should
just return an error and program can report error and let use clean or
try to recover (like powering off the machine) but calling g_malloc
everywhere is not that fine.

It would at least be fine if block drivers register some "atexit"
function to flush every buffer they possible have.

Anybody considered this problem?
