Summary:	Windows 7 guest crashes in bootstrap on MacOS X 10.6.8 host. → Guru Meditation (VERR_NOT_SUPPORTED) with a Windows 7 guest on Mac OS X 10.6.8

Did you ever boot this guest with an older VirtualBox release, for example 4.1.8?

Replying to frank:

Yes. In VirtualBox 4.1.8, it works fine.

I've corrected the summary. This problem is not dependent on the host OS, and happens at least with Windows 7 and 8 guests, perhaps others. It only happens on older Intel CPUs which do not implement unrestricted execution in VT-x.

The issue has nothing to do with the Guest Additions and is likely to be intermittent.

A fix in the recompiler that happened between 4.1.8 and 4.1.10 causes this bug to be exposed and therefore though not technically a regression it can result in either:

a VERR_RAW_MODE_INVALID_SMP guru meditation for SMP guests (see #10341 comment:1)
a VERR_NOT_SUPPORTED guru meditation for single CPU guests.

This happens when real mode guest code interrupted in an STI (or similar interrupt inhibit instruction) causes an invalid reschedule over to raw mode. This has been fixed and backported to 4.1 branch and the fix should be available in the next VirtualBox release.

Thank you for the report.

As already mentioned, the fix for this problem will be available with the next maintenance release. However, this release will take more time for internal reasons. In the meantime I can provide a few test builds which have the fix included:

For users which build their own VirtualBox packages (also Debian/SuSE and other Linux distributions), please apply r38612 to the VBox 4.1.10 sources. It will apply cleanly and will fix the problem.

I have the same problem booting Windows XP in Virtualbox 4.1.10. My CPU is Intel Core2 6420

Thanks a million! Your update solved my problem!
