Not a crash I'm familiar with, but if the register and assembly dump is to be believed, that looks suspiciously like it's trying to deref a null pointer. You might want to raise a BugTracker ticket for this.

Random notes:
  • Extension pack has not been installed (so no USB2 support).
  • I see you appear to have VT-x enabled in the VM, though it's disabled in the host BIOS.
  • You have IO-APIC disabled in the VM recipe, it might be worth turning this on.
  • Your host only has 3GB total RAM, 2GB available. So 1GB to the VM takes quite a lot of your available RAM.

Code: Select all

00:00:00.652938 HMR3Init: Falling back to raw-mode: VT-x is disabled in the BIOS.
I would first enable VT-x ( hardware virtualization ) in your PC bios.

Why? A null pointer deref is a bug whether or not you found a workaround. The software should never crash under any circumstances.
