Thanks for providing that logfile with full debugging enabled... It provides a great amount of helpful information.
A lot of the information in there aligns very closely with a known guest software incompatibility we've seen several times before. It could affect any virtual machine which has:
1) Windows 7 32-bit with recent updates installed,
2) An old driver installed – most often it would be a copy-protection driver used by software protected by Aladdin Systems HASP or some other copy-protection scheme, or old versions of antivirus programs; and
A VM meeting both of these conditions might encounter this fault during startup. The problem might surface for the first time after you install Windows updates or when you install some piece of copy-protected software or antivirus software inside the guest.
The problem arises due to a particularly dangerous "hook" technique used by certain old kernel drivers which is incompatible with recent Windows 7 x32 updates. 64-bit versions of Windows are not affected by this particular problem – although 64-bit versions can certainly fail with a similar-looking error message for other reasons!
The trace in your log file looks almost identical to a trace we've had in a Support Request involving the haspnt.sys device driver used for copy-protection... It looks so very similar that I would be inclined to suggest that it's very likely the exact same cause.
Resolving the problem will require either refraining from installing Win7 updates, or updating/uninstalling the software which is using the problematic driver.
Hope this helps!
