I tried the 32 bit one (without developer tools) on VirtualBox on Windows 7. It panics with this message:
Unknown error creating VM -
VERR_VMX_MSR_LOCKED_OR_DISABLED
That looks more like an issue with your machine. Does your CPU support VT extensions? Or they might not be enabled in the firmware. You can also fall back to traditional trap-n-emulate virtualization by disabling VT and nested paging in the VirtualBox preferences.
