Why my virtualbox always killed by signal 11 (SIGSEGV) ?

The last time when this problem emerged is today, i keep a virtual machine running and went to sleep, but after i wake up, i found it disappera, then i found the report follow.

Sometimes i running a BackTrack5 linux using virtualbox, when i start some tools like msf, the virtualbox process will kill by signal 11 too.

can any body tell me why and how to slove it ?

Windows crashed ;-)

Do you have to run VirtualBox as root?

so many people says that alway login as root is silly, but i haven't got any terrible things happened for many years, so i think it may be safe as this computer is mine and no body will use it but me. people around me can only know how to handle windows.

whether the reason for the crashed windows is that the system think it is foolish for me to login as root ?

Windows guest should not be able to make the virtualization have a sigsegv.
You re looking at a bug in virtualbox. You might report it to them.

Virtualbox has in recent years also had driver bugs causing host kernel panics.

If you need graphics performance, then virtualbox wins, otherwise consider switching to kvm/libvirtd/virt-manager.

I have no objections to running as root, so long as you accept the responsibility to make no command typos.

No - a guest OS malfunctioning should never cause the virtualization to take a sigsegv. That sigsegv means there is something wrong with virtualbox.
