Hi, I am trying to install Windows 8 in Virtualbox on a 32-bit FBSD host. (FreebSD 8.3 and VB 4.1.18). Windows refuses to install and this is due to NX not being present (it is enabled in the virtual machine settings). NX is also enabled in my bios as can be seen in the boot log of the FreeBSD host: CPU: Intel(R) Core(TM)2 Duo CPU P9700 @ 2.80GHz (2793.02-MHz 686-class CPU) Origin = "GenuineIntel" Id = 0x1067a Family = 6 Model = 17 Stepping = 10 Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE> Features2=0x408e3fd<SSE3,DTES64,MON,DS_CPL,VMX,SMX,EST,TM2,SSSE3,CX16,xTPR,PDCM,SSE4.1,XSAVE> AMD Features=0x20100000<NX,LM> AMD Features2=0x1<LAHF> TSC: P-state invariant When I create a new virtual machine with the xact same settings as the W8 host, and boot a FreeSBD installation CD, I see that none of the AMD features are exposed to the guest os: CPU: Intel(R) Core(TM)2 Duo CPU P9700 @ 2.80GHz (2883.13-MHz 686-class CPU) Origin = "GenuineIntel" Id = 0x1067a Family = 6 Model = 17 Stepping = 10 Features=0x783fbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,MMX,FXSR,SSE,SSE2> Features2=0x209<SSE3,MON,SSSE3> TSC: P-state invariant Is this just not supported, or is there a secret setting? -Guido
