VT-x not enabling

[emiller12345]

Trying to get VT-x working eventually with Virtualbox.
Running Lucid-x64 fresh install... with a brand new processor, retail sealed box...

Boxed Intel® Celeron® Processor E3500 (1M Cache, 2.70 GHz, 800 MHz FSB) LGA775
Socket    StepTDP        Ordering Code    SpecCode    HalogenFree    VT-x
LGA775    65Watts        BX80571E3500    SLGTY        No        Yes

...Made sure VT is enabled in the BIOS...

BIOS 
-Security
--XD    ENABLED
--VT    ENABLED

Now to check if VT-x is enabled

FROM: http://www.howtogeek.com/howto/linux...r-supports-vt/

...It’s quite simple: We’ll need to take a peek inside the /proc/cpuinfo file and look at the flags section for one of two values, vmx or svm...

$ cat /proc/cpuinfo | grep "vmx"
$ cat /proc/cpuinfo | grep "svm"
$

Anyone know why VT-x is not showing up as available in the OS? Any suggestions?

I set the VM to directly enable VT-x...

$ VBoxManage modifyvm 64bitTest --hwvirtex on
$

Running Natty 11.04 x64 guest OS I get

This kernel requires an x86-64 CPU but only detected an i686 CPU.
Unable to boot - please use a kernel appropriate for your CPU.

I figured out what the problem was. VT-x in Virtualbox requires 3 things to work. First, you need a processor that is VT-x capable (check, just got a brand new one). Second, you need an OS that is VT-x capable (Ubuntu - check). Next, your motherboard needs to be able to recognize VT-x. My MOBO wasn't able to recognize the VT-x part of the new processor, but was still able to use the processor. A BIOS update fixed everything.
