Could be, you'd have to go thru the OSE sources to find out, anything polling like mad isn't healty :D in the old days you had that with continues keyboard polling until someone wrote a driver that blocked 99% of them turning them into sleep calls, technically you could do the same if this really is the issue or alternatively hack the sql config.

Honestly can't do any of that, its faster just to revert to older SQL server version (trying that now). I am going to file a bug with all info I found, so at least this would be tracked.

Bug ticket created: http://www.virtualbox.org/ticket/3613

Please go there and add additional information to make it more solid. Because it seems that more programs are going to use this high precision timer feature in the future.

I have similar, but not identical behavior with different version: VirtualBox 3.0.8. Would it be appropriate to post details about it to bug ticket 3613? It is the same problem - high CPU consumption when idle 2008 SQL server is present. Running other VMs by side doesn't help.
