[SOLVED] i686?

khajvah · 2012-04-25 07:53:17

Hello people

Today i wanted to install gentoo on virtualbox but it says that i have i686 (i downloaded AMD 64bit) but i remember that i installed 64bit version.
And "uname -a" returns this:

Linux khajvah 3.3.2-1-ARCH #1 SMP PREEMPT Sat Apr 14 09:48:37 CEST 2012 x86_64 Intel(R) Pentium(R) 4 CPU 3.20GHz GenuineIntel GNU/Linux

What is the problem?

BTW, it is few months that i am using linux so i may sound dumb.

Virtualbox allows you to choose the architecture of the virtual machine.

How can i choose ? I looked in settings of virtualmachine but couldnt find.

Either when you're creating a VM, or from the "General" tab from Settings.

Have you ever run a virtual machine on this computer? Reason why I'm asking is because it would seem that you have a processor which doesn't support virtualization.

There is only one gentoo (without 64bit).

I remember i ran vmware on windows but i was running 32bit windows...

Anyway, thanks for help...

Apparently your CPU is 32 bit and doesn't support VT-x.

But then how are you running Arch x86_64? According to Wikipedia, "... In contrast, the initial Prescott chips (February 2004) did not enable this feature. Intel subsequently began selling Intel 64-enabled Pentium 4s using the E0 revision of the Prescott core, being sold on the OEM market as the Pentium 4, model F." So you may have a very early 64 bit Intel CPU, which Oracle probably didn't run enough tests on. You can either stick with Gentoo x86 or take it up with the VirtualBox developers because it seems to be detecting your CPU as 32 bit (which is understandable as some revisions are 64 bit, some aren't). It's probably why you don't see any 64 bit entries in there.

Edit: Here's another interesting bit: "On November 13, 2005, Intel released two models of Pentium 4 (Model 662 and 672) as the first Intel processors to support VT-x"

VT-x acceleration (or AMD-V) is not a requirement to run a VM, but still nice to have. Which model do you have?

DSpider, as reported by uname is his original post, his processor is capable of the x86_64 instruction set. His processor is either a revised Prescott, or Cedar Mill core; neither of which support VT. My reasoning for saying that is because those were the only two 3.2 Ghz P4 chips Intel released with Intel64. If you look at this link (scroll up for Prescott), the 3.2 Ghz cores don't support VT, although the higher end one's do. Also, this Wikipedia article states "Some guests, including 64-bit guests, SMP guests and certain proprietary OSs, are only supported by VirtualBox on hosts with hardware-assisted virtualization.

Khajvah, it seems that the only virtual machines you will be able to run are some 32 bit guests. Try the 32 bit version of Gentoo and report what happens. Take care.

I think you'll have to enable some options in your BIOS first in order to run 64 Bit Guests. I am using an i7 2600K CPU which is fairly modern but
it doesn't run 64 bit guests out of the box.

Just to add to what you said Blackout- having a setting to enable VT-X or Hardware Virtualization as it may be called, doesn't exactly mean that it will change anything. Some chips of the same socket type will be able to use that feature, while others will not. It's worth checking into though and giving a shot. I'm a firm believer in trying every avenue before calling it quits

Thanks for help, and sorry for delay(i didnt have time). I am downloading x86 version now. I will post a reply after i trying to install.

Again thank you very much, this forum is very nice forum, a lot of people who are not lazy to help others. THANKS

Yeah, x86 works, seems rogue is right,

My reasoning for saying that is because those were the only two 3.2 Ghz P4 chips Intel released with Intel64.

Anyway thanks for help everybody
