Hey guys,
Recently I need VirtualBox to install some x86_64 distros, and no matter what kind of virtualbox I installed, they all can't simulate x86_64 enviroment.
My host is arch x86_64 and I tried virtualbox from pacman, virtualbox_bin from AUR and also virtualbox from oracle site. Neither of these three VirtualBox can virtual my x86_64 distros. When I create a new machine, I can't see any 64bit version linux.
Did I do something wrong? Please help me, thanks!

I'm using virtualbox right now to emulate 64-bit hardware, what's the problem?

I can't create a guest OS with 64bit support

by the way, my cpu is Intel(R) Pentium(R) D CPU 3.00GHz

That only works for newer CPU that support VT.

I've got a Pentium D 2.8GHz and it use to be able to virtualise 64bit guest OSes in VirtualBox a while back but I guess they changed that to only support newer VT dual/quad core CPU's

Is your host OS 64 bit?
More. Info. Now.

He already said it was Arch x86_64.

Gotta be the hardware. I'm running x86_64 host and x86_64 guests.

Does it mean if I use a previous version of VBox, I can virtuallise 64bit guest OS?

Afaik it was never possible to run a x86_64 guest without VT.

I agree with Pierre, I've never been able to run a x86_64 guest in VirtualBox unless my host CPU supported "virtualization technology". Run:
cat /proc/cpuinfo
And look at your cpu flags, here's mine for example:
flags : 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 ht tm pbe syscall nx rdtscp lm constant_tsc arch_perfmon pebs bts rep_good xtopology nonstop_tsc aperfmperf pni dtes64 monitor ds_cpl vmx smx est tm2 ssse3 cx16 xtpr pdcm sse4_1 sse4_2 popcnt lahf_lm ida tpr_shadow vnmi flexpriority ept vpid
Notice the "vmx" flag. VirtualBox needs that flag present on your host CPU in order to run a 64 bit guest. There's an equivalent flag for AMD cpu's (smd I think). I'm not sure if your host OS also has to be x86_64 to run an x86_64 guest - I don't think so.
The ept and vpid flags are good to have for vbox, too.

From a VirtualBox v2.1.4 - v2.2.0 changelog,
"deactivate 64-bit guest support when the host CPU does not support VT-x/AMD-V"
When Innotek first launched VirtualBox I seem to remember it having both software and hardware (VT) virtualisation support for 64bit. Irrelevant now as it's only hardware (VT) support now for 64bit guests.
Personally, I'm over VirtualBox now that Oracle have it's dirty paws on it so back to Qemu for me...
