     1Hi,
     2
     3Unfortunately no minidump is created.

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

     13Given 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.
