HyperVisor crash? WinDbg problem?

Looks like my HyperVisor crashed. I’m running VirtualBox. This was a server 2012r2 with all updates. I find it hard to imagine my code caused this issue.

Anyone seen anything like this before?

I’m assuming it is hypervisor bug, so I will not spend any time on it. I have seen this twice in as many weeks.

It doesn’t help you, but I’m always slightly leery of issues that only reproduce on VirtualBox - there are rather too many of them for it to be purely random or “different hardware” timing related.

I’m running VirtualBox

Whenever we’ve explored a crash of our software on VirtualBox, almost without exception it turns out the be a bug in VirtualBox… to the point where we’ve put it on our “never use this” list.

Just a data point, to add to that provided by Mr. Widdowson above.
