 When !VirtualBox crashes, a file core.<pid> is created in the current directory. Be aware that core dumps can be very huge. Please compress the file before submitting it to a bug report. Or better don't attach the file to a report. Note that this core dump can contain a memory dump of your guest which can include sensitive information. Send it to frank _dot_ mehnert at sun _dot_ com if the compressed file is smaller than 5MB. Contact me directly otherwise.

-Sometimes it is required to force a !VirtualBox process to terminate, for example, a VM hangs for some unknown reason. This can be done as follows:
-{{{
-$ ulimit -c unlimited
-$ sudo echo -n 1 > /proc/sys/fs/suid_dumpable
-$ /usr/lib/virtualbox/VirtualBox -startvm VM_NAME &

-Passing the signal number 4 (`SIGILL`) is essential! The same applies to the alternative frontends `VBoxHeadless` and `VBoxSDL`.
