OSX crashes when starting VM

[caizhi]

I'm using OSX 10.10.5, and VirtualBox 5.0.0 r101573, VM is Win8.1 64bit.
There's a chance, about 30%-50%, that starting a VM will cause OSX to crash.
This problem bothers me since OSX 10.9 and VirtualBox 4.X, but when I upgrade them to the newest version, the problem still exists.

Unless you provide the crash details, quite unlikely.
