How to create a core dump ¶

A core dump is very helpful for helping us tracking down crashes of VirtualBox. To create a core dump, start VirtualBox from a command line (e.g. xterm):

ulimit -c unlimited
VirtualBox

Ensure that no startup script (~/.bashrc, ~/.bash_profile, ~/.profile) contains an instruction like ulimit -c 0 as the limit cannot be increased once it was set to zero.

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.
