#3576 fixed Windows Vista x64 causes host Mac OS X to panic during guest OS boot Kurt Raschke

#3578 fixed PAE/NX enabled, but NX (No-Execute Page Protection) still disabled -> fixed in SVN/3.1.4 Jan Ritzerfeld
Description

I created a Vista-VirtualBox (OSE) with the PAE/NX setting enabled. A few days ago, I noticed that hardware DEP is not available. In the VBox.log I see that PAE is enabled, but NX (No-Execute Page Protection) is disabled:

[...]
************************* CFGM dump *************************
  EnablePAE          <integer> = 0x0000000000000001 (1)
[...]
********************* End of CFGM dump **********************
CPUMSetGuestCpuIdFeature: Enabled PAE
Logical host processors: 2, processor active mask: 0000000000000003
************************* CPUID dump ************************
         RAW Standard CPUIDs
[...]
PAE - Physical Address Extension       = 1 (1)
[...]
         RAW Extended CPUIDs
[...]
PAE - Physical Address Extension       = 0 (0)
[...]
NX - No-Execute Page Protection        = 0 (1)

I did not find any helpful information about NX and VirtualBox, neither in the forums (NX is too short to search, DEP finds nothing) nor via google. So I do not even know whether DEP/NX is really supposed to work with VirtualBox (OSE) and Vista.
