| | 1 | Hi, |
| | 2 | |
| | 3 | Unfortunately no minidump is created. |

| | 5 | As before I noticed in '''/var/log/messages''' the following message when the VM crashed - see the '''segfault''' at line 1: |

| | 13 | Given the above, I generated a VirtualBox core dump following these instructions[1]. Without any debug symbols, it may be useless but perhaps it'll get us started. |
