Just wanted to download VLC Media Player, but the VM suddenly stopped working. Someone explain this part of the log to me?!?!
(i only posted the parts which seem to cause the crash)

This is going to discuss the host OS, which I assume is Windows. Topic therefore does not belong in "Windows Guests", it belongs in "Windows Hosts".

VBoxSVC is a background process on Windows Hosts that provides common services to all running VMs, including (I believe) the graphics acceleration API. For some reason the VBoxSVC process either locked up or was deliberately killed/crashed. I've never heard of it locking up, so I'm going to assume the latter.

Since you were running VLC, I'm also going to guess that the cause was a buggy host OpenGL driver, since that is also used for accelerated video overlays.

Please confirm the host OS and perhaps indicate the graphics card make.

Any further discussion will require the complete VM log, zipped and attached here.
