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.
