Windows 7 - Virtualbox not working with 64bit guest

Dinesh · 05-25-2010

Hi, I just installed the latest version of virtualbox. When I try to add a VM with Ubuntu 10.04 as a guest, I get this error.

It says you are running Seven 64bit which means you have a 64bit processor, obviously, so it should work, but it says you have a 32bit processor in the error which is strange.

Have you set the guest OS to Ubuntu 64bit not just Ubuntu; make sure it's Ubuntu 64bit.

If you are running a 32bit version then you can only install 32bit OSs on top of 32bit OSs not 64bit OSs.

Hi Oli, thanks for the reply. There is no option to set the guest OS as Ubuntu 64 bit. I have also checked at Virtualbox forums. This seems to be the biggest bug in Virtualbox and there is no solution for this ATM.

That really sucks.

Stick with the Sunbox Version.

The oracle version is far from ready to be released. It's just a bugfest.

Well, pretty much it's still the same, but kind of not. Oracle bought out Sun, so the newest VirtualBox is now under Oracle development, and it's now called Oracle VM VirtualBox instead of Sun VirtaulBox, or just VirtualBox.

So it's in that annoying stage of trying to rebrand something while adding new features, effectively putting it back into beta?

What's Solaris going to be called now too?

Dinesh, does your processor have VT-x extension? If so, just tick the VT-x/AMD-V Virtualization Acceleration option in VirtualBox. FYI, you need to have VT-x/AMD-V to be able to virtualize 64bit guest OSes. I have OpenSUSE 11.2 64bit running as a guest right now, using VirtualBox 3.1.8 r61349.

Edit: I just read Intel's Doc about your T5500 here, it doesn't support VT-x, thus you won't be able to virtualize 64bit guest OS. You can virtualize 32bit guest OS though...

Now that explains the mystery. Thanks for the findings.
