Hi,

when running VirtualBox inside of a Win8.1 x86 VM (which itself is running in another VirtualBox instance on a Win7x64 host) I am sometimes getting an unhandled "Application error". In the test today I created a test 32-bit VM (without a hard drive attached). I started the VM and then after a few seconds powered it off. The error occurs not always, but once every 5-10 attempts.

The screenshot and the logs are attached.

Thnx!

Nested virtualization is not supported.

Because of that, VirtualBox falls back to software virtualization and this component is buggy.
